Chirp signal in matlab
Web1) create a signal based on a given equation/formula where the frequency is exponentially decaying (based on the formula 1/exp) 2) be able to type in the starting and ending frequency along with it's duration in seconds example … 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.
