Resetting time to Zero.

[acolel]

Hi! 

I have an equation for a very specific pulse shape that I want to simply display on a waveform chart. Its given as function of time so I simply used the formula waveform VI. The equation is a polynomial. The tricky part is this I want it to graph the pulse for 1second and then just repeat it over and over. To do that I would need to reset the time (t) to zero every second. How would I go about doing that? 

Esentially I have some functon F(t) and instead of t=0-infinity I want to make t=[0-1] and then repeat over and over.

Use T from 0 to infinity to PLOT the results.

Use (T mod Period) to feed the time to your polynomial evaluator.

The QUOTIENT and REMAINDER will get you the value of (T mod Period)

Alternatively, Simply take the waveform and BUILD ARRAY, with as many copies as you need.

Can you show us your code.  I'm not fully following what the problem is.  There is a Reset input the the Formula Waveform.  That would cause the waveform to start back from 0.

This is the file. So I just want it to output that pulse (from t=0-1) over and over again, but if I simply put it in a loop it'll evaluate it for t>1. Basically I would like to reset the time back to zero after each loop if possible.

Thanks!

 if I simply put it in a loop it'll evaluate it for t>1.

Did you actually try it ?

The RESET is triggered by a RESET switch (which you don't use), or a FIRST CALL function.

The FIRST CALL will only be true on... ahem... the first call.

So it might not reset like you think.

Like I said before, there is a Reset input to that function.  Just wire a TRUE to it.
