Hi!
Ive generated a wave in a numerical model using a chirp signal and collected the responses of the model in chosen points. How can I plot properly the 2d fft of this data. The responses are in attached mat.
Here is the chirp signal:
t2=0:dt:(2e-4)-dt;
signal2 = chirp(t2,0,9.99900000000000e-05,1e6,'linear');
Is the attached image correct?
thanks in advance
