WIDTH of RMS in milliseconds

Hello

I have a question which I can not resolved. I used the function calls ChnRMS (XW, Y, E, RMSWidth) and users if they wish, can change the RMS width in percentage. But now they want to specify the width in milliseconds and I need a script for milliseconds in percentage change. What can I do?

Thank you.

Hi Sara,.

You can convert the time window in seconds to the window required in % with the following equation:

L1 = NOC ("Time_Front")
% = (CMax (L1) - CMin (L1)) * SampleRate_/100

It would also be possible to create a custom dialog box that does this automatically and have your username jump to the top of this dialog box instead of the RMS ANALYSIS dialog box, but there is no way to customize the appearance or behavior of a function of ANALYSIS expedition.  We could take hostage the ANALYSIS icon for the calculation of RMS and have this call to the top of your custom dialog box, though.

  • Calculation of RMS through a rectangular window with gap of time 25%

    Any signal (for example the sinuses), I need to calculate the RMS value, with an integration time of 1 millisecond , through a rectangular window, with a gap of 25%.
    In other words, instead of calculate an RMS value by considering every 1 ms interval, I need to calculate the value of a 1 ms window, then apply a gap of time 25% (of the window) and calculate the next RMS value assuming a 1 ms interval and so on.

    For example, in a 1 ms window, there is a 75% overlay.

    I appreciate all help.

    Thank you in advance.

    Hello.

    It has been long since I last posted something.

    I managed to get what I wanted, now I need to optimize it.

    I simulate a sinusoidal signal and I get a 1 MS integration time 't' just setting the number of samples n and the "fs" sampling rate (fs = N / t <=>t = N / fs). Can I use the tool "Extract the Signal Portion" and I calculate the effective value of the part in a loop.
    Anyone know if there is a way to do the same thing without the 'extracted signal part', because this tool using too much memory if the duration of the treatment is just too long with 4 k samples and 4 M samples/second.

    Thank you.

  • Generate PWM signals with 1.5 ms pulse width

    Hi all

    I'm working on a project where I need to generate a PWM with a pulse between 1.3 and 1.7 width ms to order a servo rotation continues.  LabView is in communication with an arduino Uno microcontroller by LINX.  My original plan was to use the milliseconds of wait function in LabVIew to do this.  I put the PIN PWM high, wait 1.3 or 1.4 ms then set the low axis for 20 less ms pulsewidth.  before repeating.  This is how I have gnereate one using the Arduino IDE pulse width, so I thought I'd be able to do something similar here.  However, as I'm sure is already obvious to anyone who reads this, the milliseconds waiting finction in LabView only accepts the whole entries.  Arduino IDE is similar, but there is a delayMicrosecond function that can be used, so if I want 1.4 ms I use 1400 US snf then convert it in ms for the 20 least part.  How can I do something similar in LabView?   Also. When I run the program as what with a 1 ms pulsewidth I have a strange behavior.  It in fact generates a PWM signal, somewhere between 0.75 and 1.25 ms and with a period between 50 and 54 ms, it turns into a model each about half a second.  I'm using LabView 2014.  Any ideas?

    You can't get that kind of resolution with Windows and any delay you specify will have considerable jitter due to Windows. If you can pass values with Linx and allows the arduino to control them, stick with that.

  • Acquisition of Digital Data Output: generate a pulse with a specific width (depending on time)

    How can I generate a digital pulse with a specific width? I was not able to find examples online. Thank you!

    With the USB-6000 - essentially none. He has only digital software programmed according to i/o. on your system, you may be able to generate impulses at speeds up to a few hundred Hertz, but there will be a considerable amount of timing jitter. Tens of milliseconds can be common and even longer variations may occur occasionally.

    Please indicate which are the times for your impulses, so someone may be able to provide recommendations specific to your needs.

  • Launch an RMS order form directly

    Product: ORM
    Platform: Form of Oracle 10g

    I'm looking for more help to launch a form of Oracle RMS directly passing a parameter in the URL and by substituting the login form of implementation mentioned in the config file.

    For Ex: Here is the URL format:
    http:// < Server >: < port >/Forms/frmservlet? config = < config_value & gt;
    Now, this opens the form that is mentioned in the config file usually the login form.

    Now here's the syntax of the value substitution...
    http:// < Server >: < port >/Forms/frmservlet? userid = < user_id > & Width = 950 & Height = 685 & separateFrame = true & Form = < form_name.fmx & gt;

    Now, when I run the present, I get an error saying
    "FRM-40010: < form_name.fmx > cannot read."

    This form is present in the default directory of the forms and is only a form of oracle deployed as it is a form which is part of the request of ORM.
    The same was mentioned in the FORMS_PATH variable as well.

    Could someone guide me through.
    Also is there a way of method calls to the form from the URL and pass parameters to the same.

    Any help is greatly appreciated.

    I have the form you call is part of ORM, then you must keep the config = party in your custom url.

  • Column width of the mailbox in the Mail of Sierra application

    Hello everyone,

    After the upgrade to Sierra, everything went well, but a strange and annoying defect in the Mail application: I've enabled the display of three columns (mailboxes, the list of messages, the content of the Message). Well, the column of the mailbox does not keep its width, restore continuous width stretched, whenever I close the application window.

    If I expand the column to display the full name of my multiple email accounts, this preference is lost whenever I close the window. Strangely, if I exit the application without closing the window and then that I raise, the width is maintained, but it is ready to be reinstalled the next time I have everything simply close the window... is possible to make it permanent? The other two columns do not exhibit this problem and their width is however maintained, even if I close the window or quit the app...

    Thanks for your suggestion,

    Enrico

    Hi Enrico,.

    I understand that you are having problems with the column width of mailbox remaining the same size when you close the Mail application window. I use the Mail app all the time so I can understand your concern. We will be that we can do.

  • width of the window

    Years, I found code or an addon that allowed me to change the minimum width of a window of firefox. I've searched and searched but I can't find it again. I think that I did by adding the code somewhere but just can't remember or find. So, how can I change the minimum window width in Firefox?

    The file type of the file is OK (Cascading Style Sheet), but the name is wrong and must be userChrome.css with a capital 'C'.
    You must also create a chrome folder (note the tiny chrome in this case) and move the userChrome.css file in this folder.

  • How can I incease the width of column in the google search results?

    The search results show all the words and the URL so I want to be able to increase the width of column - I can't see an icon that allows me to do

    The full URL is in the link, and an extension script or a user could replace the short green text (< name > element) with the full link, but I suspect it should be customized wrote, I don't know that you won't find anything in that direction right now.

  • 38.2.0 Linux Thunderbird does not width of the main window is normally paramèters

    Last update prevents the resizing to a width that corresponds to the main Thunderbird window screen. The minimum width seems to be limited to an abnormally high value, which means that it is impossible to get a normal screen. The width can be increased without problem.

    After further investigation, I found the cause of the problem.

    It was the FoxClocks addon v 4.0.2. v v 3.4.14.1 the previous works very well and allows the main Thunderbird window to be resized normally; v4.0.2 doesn't.

  • Can I change default display width in the integrated PDF Viewer?

    I almost always want to view a PDF in "page width" but the zoom default 'auto' setting always displays them to fill the height rather than the width of the window and I have to modify manually every time I find a PDF file. Can I change this setting somewhere?

    Hi cfcentaurea, you can define a view by default as follows: enter Subject: config in the bar firefox address (confirm the message information where it appears) & search for the preference named pdfjs.defaultZoomValue. Double-click it and change its value to the width of the page (this should affect all new documents you open).

    How can I make the length of each line of striking more Monzilla Thunderbird

    This line begins with a space, deliberately, and I hope that this demonstrates a known issue. Now, I would really like to see one of these systems that does what you describe. I think that you will realize that the answers of the absence of loan "do this" means that none of the regular aid here has witnessed or suffered from this problem and we are all a bit of a loss as to what makes.

    A recent post on this forum has been creating strange messages, and e-mail notification on his assignments have also affected, display (like maybe your typing) as a long line that exploded outside the framework. In his case, he used a style a little old game of indenting the first line of its paragraphs. A life habit, no doubt and he saw no reason to stop doing it.

    Other odd assignments in email seem to relate to the mail client was used to generate the message. I don't know what they inserted in the message to break things, but still long lines are the result.

    The point of these ramblings, is that you can do something that feels perfectly ordinary for you, but was not intended by the developers of the software. My mother, bless her, was formed as a typist and could never get his head around the idea that a computer will (normally) put in line breaks for you. She couldn't resist pressing return at the right margin. Obviously, you do NOT do this, but I don't think that we know what is happening or how to fix.

  • Images are the scale is no longer with (img {max-width: 100% ;}) css from the 34.0.5 in firefox update, it still works fine in IE and chrome.})

    My site was working fine up until firefox updated 34.0.5. Now the images will not scale to fit the box more. I use flexbox so that the site is changing to adapt to the size of the browser. In css, I set img {max-width: 100% ;} and this would make the jpg file size automatically to fit the area they were in, but no more than Mozilla really screwed up this with updated 34.0.5.} My site still works fine with IE and Chrome, but 70% of my web traffic using firefox so I would really like this to work in firefox.
    Any help is greatly appreciated!

    I work by setting a special parameter in CSS for the images that I needed to scale and then I have it referenced by SPAN for each img in HTML, not quite how I wanted it to work since now images filling the box even with monitors really big format, which means that they could now be blurred on a 4 k monitor but firefox left me no choice. Looks like I have going to aid in future chrome like firefox really shit the bed on this 34.0.5 updated

  • How is it possible to a certain width (number of letters) of a single line in a text of the email to send?

    I was informed by a beneficiary of my email my email is spread too wide and too hard to read.
    Is it possible to set a limit to the width of my text (or the number of letters)?
    Thank you for the support in advance.

    Hmm. There are places on the Web where the space is not allowed, specifically in URLs and a symbolic representation, such as % 20, is used. If you have been picking them up, an email client cannot see an opportunity to break the line as those offered by a real space.

    However, these lines incriminated look like OK you in Thunderbird before you send them off? When I worked with other users reporting this issue, we saw nothing wrong with the sent message and concluded that the problem is at the end of the recipient. This affects all of your contacts, or just a select few? Are they by any chance using any particular email client or Viewer?
