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

WebThe matlab for this chirp boils down to the following: function x = chirp(t,f0,t1,f1); beta = (f1-f0)./t1; x = cos(2*pi * ( 0.5* beta .* (t.^2) + f0*t)); We can replace this real chirp with a … 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.
