WebDescription. y = chirp (t,f0,t1,f1) generates samples of a linear swept-frequency cosine signal at the time instances defined in array t, where f0 is the instantaneous frequency at time 0, and f1 is the instantaneous frequency at time t1. f0 and f1 are both in hertz. If unspecified, f0 is 0, t1 is 1, and f1 is 100. WebNow, I am not familiar with python, but the chirp function in matlab produces a real signal rather than complex one. That is x 2 ( t) = sin ( 2 π ( α t + 0.5 β t 2)) In that case, you will get different results. However, you can use the Hilbert transform (I guess this is in python) which, given x 1 ( t) will produce x 2 ( t) using fft. Share
