How to re - sample a table at the right time?

I have a DAQ that returns data for each layer as a vector line (table 1-D), as the sampling rate is defined by the user, so I know the dt between each data point in the table.  I take 1000 samples at 10 kHz.  However, when I draw this picture on a waveform graph, the time scale goes from 0 to 1000 (the index of the item) instead of 0 to 0.1 s (time).  I need to get this dt incorporated into data, so when I draw it appears correctly, vs time and so I can perform an FFT to obtain the frequency content.

Use the waveform to transform your data waveforms.  One of the entries is Y (your data), another is dt (time/sample).  You probably don't care the T0.  You can then take the table of waveforms for the chart and the time will be there for you.

  • How can I turn off screen at the right time?

    Hello.

    This my first post here so please, be gentle.

    I have a Lenovo Ideacentre running Windows 7 Home Premium 64-bit with 4 GB of RAM desktop all-in-one.

    The display turns off always 15 minutes regardless of what happens in the "Power Options" which is very frustrating. I understand that the default setting of 15 minutes is used for laptops to save the battery, but it is also used on my all-in-one, even though I normally put the time in 5 hours Power Options. I can not also bring the display back unless I press Ctrl + Alt + Delete. I'm not sure but I think that this problem started after installing the latest Windows Update.

    Does anyone know of a solution to the please my problem? (I just want to be able to adjust the display time I want it to be and is limited to 15 minutes to an hour).

    Excellent, well that was my first guess at least.

    It seems strange to me that the screen saver option set initially, but later it was power settings (no screen saver) who came back.  So I will at this stage to guess that changing the value of the new screen saver is more would all good, no?  If something has changed your power options, but this isn't a strategy of e-mail server and is not the screen saver.

    I think that at this point I could try to create a new power plan (link on the left side of the power options page) and see if activate a new plan of costs it will keep coming back.  Even if something like an old registry value exists, it should apply to the former regime.

  • Insertion of records in two different tables at the same time?

    Hello everyone, I have question about inserting records in two different tables at the same time, I'm looking for is by the way a unique id, which is created in the first statement insert to the second insert statement. Example of this problem:

    < cfquery name = "addRecords1" datasource = 'test' >

    Insert Into Table1 (name, Date, age)

    Values (< cfqueryparam cfsqltype = "cf_sql_char" value = "#arguments.) "Name # ' >.

    < cfqueryparam cfsqltype = 'cf_sql_date' value = '#arguments. "Date # ' >.

    < cfqueryparam cfsqltype = "cf_sql_int" value = "#arguments. Age #"(>); "

    Select SCOPE_IDENTITY() as RecID;

    < / cfquery >

    < cfquery name = "addRecords2" datasource = 'test' >

    Insert into Table2(Company,City,Date,ID)

    Values (< cfqueryparam cfsqltype = "cf_sql_char" value = "#arguments.Company #" >,)

    < cfqueryparam cfsqltype = "cf_sql_char" value = "" #City # ">,"

    < cfqueryparam cfsqltype = 'cf_sql_date' value = "" #Date # ">,"

    ( < cfqueryparam cfsqltype = "cf_sql_int" value = "How to pass RecID to insert in this table?" >).

    < / cfquery >

    In this example, I'm inserting records in table 1 and creation of IDENTITY SCOPE as RecId. I would like to pass this id and insert it in my table 2. This Id, I'll use in my second table as an identifier. If anyone knows anything about this please let me know. Thank you.

  • How can I recover my pc for the first time that I bought?

    Hello
    How can I recover my pc for the first time that I bought? because my pc is so slow... I have a compaq laptop cq61... and I want to set up the first time... How can I?  I don't have a recovery disk because when I bought it dosnt have a recovery in it disc. Please help me. Thank you

    Hello

    I'm happy to help you

    Glancing at the screen shot you posted, your looks of partition fine recovery (recovery (D).

    Save your files on an external hard drive or flash drive (depending on how many you have).

    Once that is done, disconnect all connected to your PC, but the AC adapter.

    Start the PC and the HP welcome screen, press the F11 key to start the Recovery dialog box and follow the prompts.

    It should take 15 to 30 minutes and your PC needs to be restored to its factory settings.

    Then just reinstall all programs and files that does not come with the PC.

    You will need the files or the installation of program diskettes. You cannot back up installed programs and reinstall them using a backup.

  • How can I get this question to the right person in Sony cameras?

    How can I get this question to the right people in the Sony cameras?  The main site contact form does not have a pre-sales question:

    I intend to buy a digital SLR type that has at least 24 million pixels, 4K recording/storage/exit offers video, Wi - Fi, objective interchangeable with anti-shake zoom function and which allow me to save my pictures in full form, so that I can view in 4 K on a Sony 4 K TV.
    Looking at the picture of the cameras is intimidating.  I prefer Sony.  Can you point me to one of your cameras that meet my needs?  If there is on the way before the month of may of the next year, please let me know about that as well.  In addition, I don't want the so-called very high prices of professional cameras, namely $5K or more.  Thank you.

    With regard to a DSLR with 4 k video, no again.
    Will there be one in the future? Yes there will be.
    When? No idea yet.

    The closest thing that currently holds the Sony is the Sony RX10ii

    DSLR body, 4 k video, built in an optical (in lens), wifi/NFC, stabilizer etc.

    However, it is only 20mp and it uses not interchangeable objectives.
    It's lens located between however 18-200mm (35mm equivalent)

    Finally, it's only a 1 "sensor, so don't expect a quality digital SLR image, but quality located near DSLR quality nonetheless.

  • How many computers which can install you programs CC on and how many computers can use programs at the same time? [was: Question for you!]

    When you buy an individual monthly plan for CC at $50 per month, how many computers which can install you programs CC on and how many computers can use programs at the same time?

    Thank you for your answer!

    You can install the software on two computers. These two computers can be Windows, Mac OS, or everyone. If you install on a third computer, you will be asked to turn off this feature on the other two computers. You can then re-enable one of the two previous computers and use Cloud Creative apps on it. You can use apps on a single computer at a time.

    How can I return it and get the right size stock photo that actually works to post 20 x 30

    Hi Debbie,.

    Once that the photos were allowed, they cannot be removed or not allowed.

    Thus, you must make sure that the image you need for your projects. You can also check the size of the images before their approval.

    Hope that answers your question.

  • can I display different tables at the same time?

    Hi all

    It is probably a newbie question, but is it possible to display different tables at the same time? I use SQL Developer 1.5.5 and I seem to be unable to display several tables at the same time, whenever I chose to open another table, the old table disappears. In other words, the Bulletin Board only switches to your new choice in the table list navigation. Any ideas anyone?

  • Why not the preferences of the general calendar for "the day ends at:" only offers the possibility of 'am' and not 'pm '? And alerts for an event from 14:00 activate at the right time, but it's at 02:00.

    The "day starts at:" options correctly offer options of "midnight" through time "am" to "noon". Thus the "day ends at:" should have options starting with "midi" and moments of "pm" to "midnight", but instead, they are all time 'am '.

    And alerts for an event from 14:00 activate at the right time, but it's at 02:00. Maybe it's a consequence of the above.
