http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/chirp.html WebUsing MATLAB or Python, divide the 400 samples of the chirp signal into 10 nonoverlapping windows, each containing 40 samples. Organize the windows into a 40 ×10 matrix, then take the DFT of each column of this matrix, thus computing a non-overlapping version of the STFT.
