chirp waveform

[shawnv1]

Hey , i am trying to make a chirp waveform in cvi for like two days and the build in function "chirp" just wont work.

this is how i implemented it:

Chirp (100, 2.0, 40, 500, chirpArr);

and this is what i see in the graph:

can someone plsss can solve this?

Hello,

I've used it long ago and it did work back then. I think you simply need to experiment a bit with the parameters.

Not a CVI guy but from LabVIEW.

Assuming NI used the same underlying dll/function in both LV and CVI, here is how the LV counterpart works,

Inputs

- samples = number of elements in the Chirp array

- f1 = start frequency / sampling rate

- f2 = stop frequency / sampling rate

- amplitude = amplitude of the chirp signal
