delay signal

[Marc.M]

Hello,

My purpose is to simulate an impulse generator, and i have some problems with the double impulsions.(see the first attachment)

I want to delay a simulation signal, and i need to settle this delay.

At the begin i try with the Y[i]=X[i-n] VI.vi and that work but it is impossible to settle it in time.

So i downloaded the control simulation toolkit and I try to use the simex  transport delay.vi It look like fine, but I can't import it in my project same if i try to transform it in subVi. (see the second attachment)

If you have another idea,I will be happy to see it.

Could you help me please ?

If your delay is in fractions of samples , no problem

If not, you can do it with a filter.

Here is a simple echo program using convolution (also in fractions of sample rate)

I sense another homework problem.

Right, should have posted the picture 😉

Hello, at smercurio_fc ->Wrong, I'm in intership and I never touch labVIEW before to start my project and my tutor dosen't know very well labVEIW.(He advice me to do a post on this forum)

At Henrik Volkers -> thank you very well for your help. But I don't know how repeat your solution indefinitely. Do you have any idea ?

Please provide more details:

What are you receiving? An array of data? A waveform? What timing informations do you have?

Still wonder why the delay.vi doesn't fit your needs...

Hello,

I'm sorry to answere so late.

I was very busy and i forgot to answer. I managed to adapt your program at my needs, so thank you.

If you want I can share my program(impulse generator) on this forum.
