Chirp scaling algorithm matlab code
WebGenerate a signal consisting of a chirp sampled at 1.4 kHz for 2 seconds. The frequency of the chirp decreases linearly from 600 Hz to 100 Hz during the measurement time. fs = 1400; x = chirp (0:1/fs:2,600,2,100); stft Defaults Compute the STFT of the signal using the spectrogram and stft functions. Use the default values of the stft function: Weby = chirp (t,f0,t1,f1) generates samples of a linear swept-frequency cosine signal at the time instances defined in array t. The instantaneous frequency at time 0 is f0 and the …
