Questions about an average of response spectrum and frequency of feeding mode.

Hello

I have a few questions about an average of mode. When I generate a sinusoidal signal from one output to two input channels channel to see if my DAQ card works well and vector averaged in the power spectrum for DFT, the amplitudes was different from the previous one of the amplitude, which was supposed to be 1 v peak. They range from 0.5 v to 0.6 v peak. When the calculation of the average model is RMS, the amplitudes were close to 1. I wonder what are the fomulas of RMS and average vector. Does that mean that I could not accurate if I use an average of vector? In a time of frequency response, why I coherences of difference and the amplitudes using the vector and the mean quadratic value?

Thank you

rico1985,

The differences in modes of generation are as they sound: 1 sample output only a sample writing, N samples will be released however many samples configure you for each entry, and the continuous samples released samples continuously until a specified user action happens (you press the stop button or a logic that you created gets fulfulled). The range of Signal output allows you to set a ceiling high and low level of your output signal and it only affects the quality keeping in this beach. Timing to set a deadline for the time between the acquisition of the sample. If a new sample becomes unavailable before the timeout setting, you will get an error. This is useful for looking at a network, because if the network goes down and you stop getting data from a machine and then you would like to know about it. I point you to those videos that are short tutorials on how to make the most of these actions in SignalExpress.The SignalExpress 3.0 Help file is also your first point of contact for all your questions on getting started. These two resources should get you up and running in SignalExpress in no time. (either by the way all your questions answered using these resources) Bravo!

  • Consider purchase of Wacom Cintiq 27 HD Touch - Questions about the tactile feature in Photoshop and Lightroom

    I'm considering buying a 27 HD Touch of Wacom Cintiq monitor. I have a few questions about the two programs Adobe and their use of the 'touch' feature - Photoshop CS6 and Lightroom 5.7 running on Windows 7.

    1 problems related to touch a feature in Lightroom and Photoshop CS6 and 5 resolved that you see on the forums of Wacom a year ago?

    2. If so, is there sufficient value gained through the tactile feature in Photoshop CS6 and Lightroom 5 to justify the $500 price difference between the Cintiq 27 HD vs Touch HD? (I realize that this is a subjective question based on the abundance of its cash).

    3. I intend to stay with CS6 as long as possible to avoid a monthly subscription, BUT I wonder if buy the Touch HD can provide additional key features in future releases of these products that do not exist currently. (It is a pie in the kind of sky in question).

    Thank you!

    Support for Photoshop Touch is added by CC 2014.2.2.  However as the Pro Intuos Wacom tablets with touch can be used with earlier versions of Photoshop and the Wacom Tablets Configurator can custom features can be used with Photoshop touch tablets.  I use LR but I don't know that the same thing would be true for her. You can configure the setting for many applications. The device driver knows which application its interfacing with and uses the parameter set for each...

    I have disable most of touch when using Photoshop.  The main reason why I have a Tablet is Photoshop Brush tools. Like Eraser, clone stamp, etc, nothing is better then a pen when it come to create the layer mask.  For most programs, I always use a mouse and I use the keyboard, the mouse and the pen with Photoshop...

    I never wanted a Cintig I do not have my hand between my eyes and the work. I'm not an artist.

  • A question about the order of COLUMN sqlplus and PL/SQL

    Hello everyone.



    I would like to ask a question about sqlplus command COLUMN that I use in order to define the length of my queries of output columns. So, for example, I run something like:
    COLUMN market FORMAT a20
    That is why any column with the name 'the market' will be composed by sqlplus as 20 characters.

    Currently I'm working on a PL/SQL script that makes this automatic procedure, in other words, instead of manually write for each column in the above COLUMN order, it uses the DBMS_SQL. He read first as input the name of the table and then inside a loop, it detects the maximum length.

    For those interested, here is the Oracle documentation page that I found (example 8)
    http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14258/d_sql.htm

    If everything worked well enough I managed to recover the maximum of each column in my table length, except that I don't know how to use the COLUMN sqlplus command in my PL/SQL block. I would like to do something like that (it's just a pseudo-code)
    FOR colIndex in 1 .. numberOfColumns LOOP
            currentColumnName = getColumnName(tableDescriptionObject, colIndex);
            currentColumnLength = getColumnLength(tableDescriptionObject, colIndex);
            
            COLUMN  currentColumnName FORMAT a -- and here after 'FORMAT a' I have to write currentColumnLenth but I don't know how to proceed.
    
    END LOOP;
    I would like to know is there a command in PL/SQL to define the appropriate column typeset in sqlplus length?


    Thanks in advance,
    Dariyoosh

    Hi, Dariyoosh,

    Sory, I don't think that there is a simple way to publish SQL * most orders fom PL/SQL.
    PL/SQL runs in the database (back-end); There isn't any direct contact with SQL * more at the front end.

    The best way I know is that PL/SQL script (myfile.sql) with orders of the COLUMN, and then have SQL * more run the script (@myfile).

  • Suggestions and Questions about the upgrade my Hardrive Mac and Ram.

    Hi This is my first time asking something in the forums. (At least I think) Well anyway, I got the Macbook Pro Mid 2012 13 "with the retina also runs the OS El captain. I do computer for school and sometimes animation video editing and ive noticed some performance as my projects get bigger and bigger issues. I want to improve my mac, but I'm not very tech savy and don't want to do something useless, so I had a few questions, I wanted to ask you.

    Do I need for my hard drive and my Ram?

    What effect will the upgrade of my Ram and what effect will be upgrading my hard drive with an SSD?

    I saw this SSD online and thought of novice opion that sounds get Id more bang for my buck (link) with her. Is this good? What more to kill? WiIll it still works? Could you suggest some other good affordable options?

    My next question if I decide to upgrade my Ram can provide you with some good affordable links to buy of new RAM sticks, is also 8 GB, the best he can do?

    My next question I watched a few videos online and by installing the updates level looks really easy and fast. But I use bootcamp (to play games sometimes), and I wanted to know if I save my files on my drive as ive seen people do videos, (something to wipe the drive and put it back in after installing updates) will be I lose my windows 7, I lost the disc to reinstall and he check so I really want to buy a new also do not want to lose the things I put in memory.

    From the retina MacBooks you is impossible to pass the ram as it is soldered to the logic board. As with the hard drive, it's just a card ssd and you can't get those anywhere because their hard to find.

  • Question about the temperature of the processor and the use of Vista on Satellite Pro M70

    Hello

    I have Satellite Pro M70-113 and it has Intel mobile Pentium 1.86 GHz CPU.
    The problem is that its normal temperature is 80 degrees Celsius... while I use the browser and other common programs...
    and recently it automatically shut off twice and pressing the button works / stop won't turn on... when I unplugged, replugged the power cord so I could only turn it on...

    And while playing games, it would of course go above 100 degrees...

    So you know what is the max temp through which the CPU can go without stop or damage the CPU or surrounding a circuit?
    I know that when I bought this laptop about 2 years back... it was not warm this...

    And by the way this laptop came with WXP Pro preinstalled and doesn't show any vista capable logo (because at the time, there was no such promotion of Microsoft, as it was the year 2005, Nov).

    Now, I use vista and upgraded to 1 GB of RAM and I have no problem using the Vista pc.

    Secondly, I did not update my BIOS to version the most recent is available.

    Although I'd love to have updated the BIOS but I worry about the bad flashing and says BIOS driver update page that the version of the BIOS doesn't support vista - whatever that means? If I go back to Windows XP Home edition after installing the BIOS for vista, the pc will not be usable for WXP or what?

    Is there any link to the processor heats to the old version of the BIOS, I'm still using... will update BIOS facilitated the temperature?

    Please answer.

    Thank you.

    Hello

    Wow, you have a lot of questions. :) If I was sort of a support guy to it all with such question much. ;)

    No, I'm kidding; with regard to your questions:

    First of all you must clean your CPU cooling with compressed air, because if the breakdown is clobbed with dust and then it s just logical that your processor is a little bit more 'hot' then 2 years before.

    The max temp is available on the website of intel. I think that the section is called "intel spec finder" or something similar.
    With Vista and bios: you need to update your bios, since then some improvements are making more compatible bios for vista.
    But don t worry, XP won´t be unusable if you update your bios, the bios-update brings improvements for vista, but does not degrade anything about XP.

    If the bios update will solve this temporary problem is not clearly, rather a cleaning as I told you will be better.

  • Question about OS preinstalled on laptops Toshiba and recovery CD?

    Y at - it only something preinstalled on Toshiba notebokes and if so, what is pre-installed? Only Windows or also the software?
    Is there a score with these things pre-installed on it? Do you get the original software CD or that you get only a recovery disk?
    I hope someone could help me with these questions.

    Thank you very much.

    HI Sanne,

    This will depend on what any Toshiba laptop model you buy, and also the provider that you use.
    Some Toshiba laptops come with recovery discs that you use to install the operating system base so that any software provided and utilities. Other Toshiba laptops have a 'hidden' partition and a utility to allow you to create your own recovery discs.

    If you buy your ook noteb through points of sale, then they may well pre = install the operating system for you as well as their own software and tools.

    In general, you will not receive an original CD of Microsoft since the laptop will be provided under an OEM license.

    As you can see that there is no simple answer to your question. :-)

  • Question about the photo (using the folders and Photos app)

    Hello

    I am new on the app Photos - aperture used briefly but never really liked. I used to manage/sort all my photos with simple folders on the hard drive. Now, I would like to move the direction of the Photos app.

    A few questions:

    1.) if I add images, are they duplicated on my hard drive when I import them from Photos?

    2.) how to delete images permanently? I need to do a cleanup, which is easier in the Photos. If I delete the images here (and also delete the "recently deleted" album), why they remain in their original on my hard drive folder?

    Any help is appreciated - thanks!

    1 - Yes by default which is highly recommended, as was the case with iPhoto you then delete the photo source since it is safe in the library

    2 - pictures works just like iPhoto - nothing outside the library is not affected by what you do in the application - see 1

  • newbie question about obtaining work web interface 3424 and 3448

    Hello everyone - first assignment in time-

    I have a 3424 and 3448 who seems to have the same symptoms.  I am able to get both working as I want, but I am unable to get either to respond to a request for a Web page or a ping.

    Here is a copy/paste of what I see:

    Console # show ip interface

    Activity of Type status IP gateway
    ----------------------- -------- -----------------------

    IP address I / F Type
    ----------------------- ---------------------- ---------

    According to my research, which should allow me to go to a browser and type 192.168.0.100 (my nic is 0.99) and access the Web page, but no Web site appeared.

    this site suggests that I should be able to ping:

    Console # ping 192.168.0.100

    but I do not see a ping response.

    I KNOW it should be easy, but I must be missing something very obvious.  after reading this I've also tried

  • Question about version first submit 1.0 and 1.1, with some corrections?

    Hello

    First of all excuse me if this question has already been answered here.

    If my app (version 1.0) is rejected due some bugs, what's the next step?  Fix it and submit the 1.1 version or do it with 1.0? In my case I presented version 1.1 because I couldn't do it with 1.0 as the application was already signed.

    Thank you

    You can not re - sign with the same version, so change it demanded. There is no need to go back to 1.1, however, if you do not want. There is up to four items to the version number. My last example is 1.0.4.1261... You could make 1.0.0.1 if you wanted.

  • Basic question about the selection of the AP and multiple channels

    I have about 10 PA (Aironet 1240 G) intended to be deployed one of my floors of office. We examined a diagram of the floor and made sure that we ordered enough to completely saturate the ground with wireless coverage. There are a few AP which are probably only 50' with each other. It's actually a bit exaggerated.

    I put a base on the switch configuration so that there are two different SSID on the access point (one for a production of WLAN and the other for a WLAN comments). Each SSID is associated with a VLAN different.

    I want to know is this what to do on the channels for the AP? Each access point will be independently configured and controlled.

    I understand that there is a way to control which channels each AP uses, but I'm not familiar with the controls or best practices for the configuration of the AP

    Can I do something like make sure that each access point uses a different channel than its nearest adjacent neighbors? Someone would mind sharing what is the command to do it, and where it is applied?

    I have read through some archives and saw people talk to set "no bunk channels" and to configure them to use 1,6,11 channels. I guess I don't understand what is meant by there.

    Manually define you an access point to channel 1, then set his neighbour to use 6 and another neighbor to use 11, and then you who stay?

    What is the worst of the scenarios on what happens when you have no AP too close to the other located on the same channel?

    It is a pleasure to read through the documentation if someone wouldn't mind pointing me to it. I'm still trying to understand the concept, and then I should be able to understand the documentation that came with the AP.

    Thank you for your help.

    If your stand-alone Access Points. If it was a deployment of Comptrollership, in fact to dynamically manage the channels for you.

    But what you really want to do, is you see APs do something like this:

    (imagine each number represents an access point, and it channel)

    1 6 11 1

    6 11 1 6

    11 1 6 11

    1 6 11 1

    It is a conceerne configuration guide. I think he has a small section on the channel assignment. If you do this manually, I think that you specify the actual frequency used in the CLI instead of the channel number.

    http://www.Cisco.com/en/us/docs/wireless/access_point/12.4_3g_JA/configuration/guide/s43rf.html

    So the CLI under the Dot11Radio0 you would do something like 'channel 2412' for channel 1... 2437 for 6, 2462

    for 11...

    If you have APs side by side on the same channel, you are likely to have clients interfere between them.

  • Question about commissioning of the E20s - CUCM and TMS

    If we now run software CUCM 8.6.2 and 4.1 E20.  I played with CUCM and TMS supply by and a few questions.

    It seems that there are some features that can be set via the TMS models that cannot be resolved via CUCM (MTU, custom, etc commands).  Is it possible to apply these settings through TMS while having the unit registered in CUCM?

    Essentially, I want my call recording platform CUCM and control, but want to keep the granularity that TMS offers in terms of commissioning etc..  I expect the same problems with C-series, etc.

    Am I right in saying that, in order to get the E20 to join CUCM, I need to define the external Manager to "CUCM", and thus eliminate any possibility of TMS to manage? Otherwise, what is I could have managed by TMS and then set the SIP of the E20 to point to CUCM via templates in TMS?

    Any tips on that?

    Hello

    Having both TMS and CUCM to manage endpoints is not a good idea (yet). TMS and CUCM will return to each of the other toes with unpredictable results.

    With TMS 13.2, I understand that you should be able to import the CUCM in TMS and then find all systems registered to it and import these into TMS, however in this case TMS plan only systems conferences and will manage them not active (you can see status of the call as well).  13.2 TMS is not yet released, so that's what I said must be in this version.

    So basically now if you use CUCM, use CUCM provisioning and don't use TMS.  We focus on interactions with systems registered with CUCM TMS and it will be more developed on this in the future.  I recommend you check out the TMS13.2 release notes released to see if it is mentioned.

    Thank you

  • simple question about access to information of predicate and filter

    Hello Experts

    I know that maybe this is a very simple and fundamental question. I read a lot of articles on explains the plan and trying to understand what are 'access' and 'filter' which means?
    Please correct me if I'm wrong, I guess when the index of explain plan can use predicate choose access if the explain command plan go with complete table filter scan (witout index) is chosen.

    My last question is, can you recommend me an article or document will contact plan to explain it in clear language and base level?

    Thanks in advance.

    Hello

    as the name suggests, access predicate is when data access based on a certain condition. Filter predicate is when the data is filtered by this condition after reading.

    For example, if you have a select * FROM T1 WHERE X =: x AND Y =: y, where X column is indexed, but column Y is not, you can get a map with an INDEX RANGE SCAN with access predicate = X: x (because you can use this condition to when selecting the data to be read and read only sheets of index blocks that meet this condition) and ACCESS BY ROWID from TABLE with the filter predicate Y =: y (because you cannot check this condition until after reading the table block).

    I'm not aware of any good articles on the subject, and unlike others I can't find Oracle enough detailed documentation. I suggest you read a book, for example Christian Antognini, "Troubleshooting Oracle performance problems."

    Best regards
