waveforms

1.how can i multiply two waveforms with different dt?

2.how can i intergrate the waveform for particulat time interval

3.how can i make hold and sample circuit for a waveform

1. How do you define the result of multiplying x(t1) by y(t2) where t1 and t2 are not equal?  The most straightforward approach might be to resample the waveform with the larger dt to match the dt of the other, then multiply the resampled waveforms.

2. Extract the Y array component.  Use Array Subset to get the time interval you want.  Integrate. Reconstruct the waveform if desired (before or after integration).

3. Extract the Y array component.  Use Index array to select the sample.

thanks!can you help me the formula which i can use to generate andom square waves using formula waveform vi

Hi fil-leep,

In order to create a formula for a square wave, you are going to have to do a Fourier transform which will be more work than I think you are looking to do.  If you just want to create a square wave with certain parameters, you can use the Square Waveform.vi or the Square Wave.vi.  I hope this helps!
