How can I calculate the waveform integral in a defined time interval?

Hi:
I need your help. How can I calculate the waveform integral in a defined time interval? For example: from "0" to "2pi"?!
Thanks.

Hello Clecio,
You might want to try the Integral x(t) VI.  The documentation for this VI notes:
Performs the discrete integration of the sampled signal X. Integral x(t) calculates a definite integral. The value of the output array at any value x is the area under the curve of the input array between 0 and x.
You would pass the samples of the waveform that fall between your particular window, then pass 1/number of samples for the d(t) parameter.
Hope that helps.

  • When I record an audio track, there is a waveform. When I stop recording, the waveform disappears and becomes a straight line. It also disappears from the track edit window. But the sound is there. How can I stop the waveform from disappearing?

    When I record an audio track using Logic Pro X, there is a visible waveform which appears as I record. When I stop recording, the waveform disappears and becomes a straight line. It also disappears from the track edit window. But the sound is still there. How can I stop the waveform from disappearing? And can I do something to view it after it has disappeared? Anyone know the anser?

    In Logic:
    Preferences/Audio Set Recording Delay to 0 <zero>
    This should always be set to zero unless a specific set of circumstances exist and you're audio drivers do not report position correctly.
    On occasion, usually when importing a Logic 9 project, Logic-X randomly changes this to a negative/positive number.  It's actually a bug in Logic, as it should always display the waveform.

  • How can I calculate the total time in java?

    Hello!
    I need to calculate the total time!
    For example I have start time:
              Format formatter1;
              Date date1 = new Date();
              formatter1 = new SimpleDateFormat("hh:mm:ss");
              String startTime = formatter1.format(date1);
              //startTime = "14:20:40";
    And I have finish time:
              Format formatter2;
              Date date2 = new Date();
              formatter2 = new SimpleDateFormat("hh:mm:ss");
              String finishTime = formatter2.format(date2);
              //finishTime = "08:30:55";
    So, after manually calculating, I get total time: "18:10:15"
    How can I calculate the total time in java? (Using formatter1 and formatter2 I suppose)
    What I need is to print "total 18:10:15"
    Thanks!

    I did the following but, I think something is wrong here:
    I defined before: Date date1 = new Date(); Date date2 = new Date();
    And it should be exactly 5 seconds between them.
    I found delta between date1 and date2:
    Format formatter = new SimpleDateFormat("HH:mm:ss");
              long timeInMilliFromStart = date1.getTime() - date2.getTime() ;
              Date date3 = new Date(timeInMilliFromStart);
              String timeInSecFromStart = formatter.format(date3);
    and I get always
    //timeInSecFromStart = 02:00:05
    But it should be exactly 00:00:05.
    What can be a problem?Because, like I said, a Date measure an instant in time, not a duration. So when you have 5000 ms, and you turn that into a Date, that means 5 sec. after the epoch, which works out to 1/1/1970 00:00:05.000 GMT.
    As I mentioned, if you're not currently in GMT, then you have to set the TZ of the DateFormat to GMT. Right now, it's showing you the time in your TZ. If you included the date in your SimpleDateFormat, you'd see either 1/1/1970 or 12/31/1969, depending on which TZ you're in.
    Bottom line: You're trying to use these classes in a way they're not meant for, and while you can get the results you want for a limited set of inputs if you understand what these classes do and how to work with that, it's a brittle approach and comes with all kinds of caveats.

  • Text on path: How can I calculate the text length?

    Hi
    I have a text on path (spline item). Now I need the length of this text and the length of the spline item.
    I try to calculate the text length using IWaxLine::GetWidth(), but this is always 0.
    - How can I calculate the length of this text?
    - How can I calculate the length of the spline item?
    Thanks
    Hans

    It would be interesting if you could describe the purpose of your "length", but I don't have an answer anyway. Would the bounding box be sufficient?
    Considering that TOP may be combined with arbitrary spline paths, this could become an exercise in higher math. I haven't yet encountered a function that returns the mathematical length of such a spline.
    Otherwise it could be solved if you iterate and sum up the relevant points of the bounding box (ascender, descender, baseline?) of individual glyphs.
    Be warned that the whole TOP looks alien, as if it were a transplant from a different program. Experience also shows that documented and actually used interfaces / commands are completely different animals ...

  • How can I calculate the characters with spaces in a document on pages

    I'm currently using pages to write my personal statement up on, although i need to keep my characters including spaces under 4000 characters and also have no more than 47 lines. I've found how to do a word count and find how many charcaters I've used, but i can't see anywhere the information that I actually need to find! Someone please help, thankyou

    How can you calculate the number of lines if you don't know how many characters there are to a line?
    This is 2013. We are using word processors with real fonts, not terminals or teletypers or typewriters.
    If you must have 47 lines then shrink the point size of the font until it fits.

  • How can I calculate the value of the cell, which depends on other rows?

    Hi, all!
    I have an application with table. In this table i have calculate some fields, that doesn't exists in data class and depends on other row values, e.g. current row number, or sum of previous rows. How can i calculate this values in TableView?
    The problem is that I have no information about the current row number in the cell value factory.
    Example:
    public class Transaction {
         public String getName();
         public BigInteger getAmount();
    } // There is no getter for "Balance"
    Result table should be something like this:
    Name
    Amount
    Balance
    transaction1
    300
    300
    transaction2
    200
    500
    transaction3
    500
    1000
    Also, after sorting by "Amount", "Balance" should be recalculated:
    Name
    Amount
    Balance
    transaction3
    500
    500
    transaction1
    300
    800
    transaction2
    200
    1000

    Strings can be converted to numbers by various parse methods. For instance Strings can be converted to double via Double.parseDouble(myString).
    That being said, it appears that your textfield will contain numbers and operators, and so these operators will need to be parsed too. I would advise you to search on the terms Java infix postfix.
