Integrals of trigger

If I have a waveform with data pre-trigger of 50% and 50% posttrigger data, is there a way to take two separate integrals, one for each of the sections?  I want to calculate the background noise for our experience.  I am currently recovering measures two different waveforms, one with 100% of data pre-trigger with 0%.  But the pre-trigger data coincide with data signal for the calculation of noise is incorrect.

I'm using a PXI-1000 b.

Thank you

Here's the old vi I am changing:

Have you tried to take the original signal with pre and post data of the trigger and just divide the table into two?  It will take a couple of functions to do this, but it's a fairly simple task.  For example:

  • MainStage stop drums trigger keyboard

    OK I have an Alesis V61 and MS3. It has 8 pads of the battery. I want to set up a very simple patch where all 61 note keyboard triggers ONLY a piano patch. I want one of the Eb trigger pads (2) - a handclap.

    I have 2 strips of channels, Yamaha Piano and Bluebird Drum Kit. The strokes I started with success of the drum pad. Everything is good. BUT the keyboard also plays samples of Bluebird, which is not good! How to stop the notes on the keyboard trigger the Bluebird Drum Kit samples? Thank you guys

    HA! After 3 hours of tinkering it worked (for me anyway). In the channel strip Inspector, MIDI input set none - kills the keyboard trigger the sample but not the pad... against intuitive but worked for me! Hope this helps someone else

  • Double integrals of first HP

    How to solve the double integrals in first HP?

    Set your first manual input (parameters, page 1, home page) mode, go into display CASES and enter the double integral exactly as you see above.  For the full symbol, you can use the model (between the Toolbox key and the x-t-theta-n key).  Even if a warning message may appear (depending on your settings), the correct result is returned to the 1/10th of a second: 1006/105.

    If you prefer the algebraic input (instead of enter manual mode) mode, type the following expression:

    int (int(x^2+y^2,y,1,x^2), x, 1, 2)

    This means exactly the same thing and gets the same response, but I personally find much more easy to read manual syntax.

  • HP 40GS stuck on the hourglass for the calculation of certain integrals

    So I used my calculator HP40GS for awhile, and I've never had problems with it.

    Recently, when reviewing for the examination of calculation AP, I noticed that the calculator could not do some integrals. Because I already went through the lesson using the graphing calculator calculators and integrals without problem using my computer, I don't think that there is nothing special about this one.

    One of the integrals in question is 3 * e ^(-x/2) * sin (2 x) on the interval [0,2].

    I tried to make the home screen capture (in the mode of operation):

    ∫ (0,2,ABS (3rd ^(-x/2) * sin (2 x)), x)

    The calculator has been blocked at least five minutes on the same screen with the little hourglass until I pressed on 'on' to force her to leave.

    Also, I tried to do this in CASE mode, using the manual view. This also does not work.

    Other calculators in the classroom (TI-83) did the integral almost immediately.

    My memory is not yet close to being complete.

    Is there something I could do or check to solve the problem? Other integrals seem to be more or less fine.

    Thank you!

    When you do digital integrals, some of them may take some time. On the 40gs and many other units of HP, the accuracy of the correction is what distinguishes the accuracy of assessment. Try to set the precision of DIFFICULTY 4 in the homescreen of modes and re-evaluate. I suspect that he will return very quickly. That should mean "exact to 4 decimal places.

    You can also try to do exactly in the CASE and then to assess the result. In many cases, it may be faster.

  • 50G and problem with integrals, new user.

    Hello! I am a student in electrical engineering and I bought a 50G as my first graphing calculator, since that's what most teachers recommend here. I have colleagues who use the same who also make things a little easier, but I have almost no experience with it.
    I serve the 49G and first emulators recently so get used to RPN, and while the first gives me the right answer, my physics 50 G and the emulator of 49 G give me something weird.

    Well, if I'm trying to incorporate "exp (x ³) dx" for example, the calculator gives me "exp (x³t) dxt" on the screen.

    Most of the integrals worked out of the box, but some have this exact same behavior.

    Because the emulator of 49G and 50G physical give me the same thing, I suspect that it is just a matter of configuration. First emulator gives the answer however.

    Here a few photos:



    Then request EVAL:



    And 49G emulator:

    This doesn't seem to work in the latest iOS Update 9.

    I would be fine with a hotkey, or have to invoke the keyboard of the shop, then press the button of the microphone, but I don't see how do either.

  • Electric trigger DAMA IQ & check for new records to collect an infinite number of records

    Hi all

    I have some difficulties with the help of the trigger edge power IQ & questioning the DAMA if it has samples/records ready for pick up.  I have reviewed the documentation on the support to the screw and the examples provided with the driver of the ACCA and have not been able to solve my problem on my own.    What I'm trying to do, is to have this VI capture periodic RF bursts that are larger than a specified threshold.

    I go to this topic in the following way:

    I put the number of samples I captured (finished) for each burst which crosses the threshold
    I put the number of records to capture to be infinite
    I said that the rising slope and the appropriate threshold
    I have then to validate the configuration of the ACCA and start acquiring
    I have then go into a loop and check the backlog of samples as well as the acquisition is
    If either of the above is true then I get the samples with the IQ extract complex WDT vi
    I continue looping until the user stops the vi with a button on the front panel
    I went on this path that I didn't block indefinitely or for long periods of time

    What I see is:

    I'll take one shot and then nothing else
    what the samples never back above zero
    that acquisition is ever complete
    If I switch out the IQ extraction with equivalent IQ reading and ignore the completion back & I get documents like I expect

    My understanding is as follows:

    Electric trigger IQ does not have to be re-armed in VI
    that each trigger to fire IQ Power will create a new record containing the number of samples that I asked

    My questions:

    It seems that when the number of records is infinite that the acquisition is never considered as carried out when the State of the acquisition is verified, is that correct?
    I receive multiple records pending upward on the ASB using this configuration?
    Why a record number is provided with the back of fetch get VI?
    Why would I pick any folder, but the record of zero?
    I'm doing something wrong here?
    Is there a better way to do this?
        
    Thank you
    Russell

    Hi Russell,

    You are on the right track to get your application do what you want. Instead of check to fetch back, I suggest that lets you read the property node DAMA the "' Acquisition > Fetch > Records made" property to know when a new record was acquired. "

    > it seems that when the number of records is infinite that the acquisition is never considered as carried out when the State of the acquisition is verified, is that correct?

    That is right.

    > I get multiple records pending upward on the ASB using this configuration?

    Yes

    > Why a record number is equipped with the rear of fetch get VI?
    > Why would I pick any folder, but the record of zero?

    You ask DAA for an infinite number of records. File 0 started the first trigger seen. Record 1 to the second outbreak (end of disk 0) and so on.
