WebThe python module Matplotlib.pyplot provides the specgram () method which takes a signal as an input and plots the spectrogram. The specgram () method uses Fast Fourier Transform (FFT) to get the frequencies present in the signal. The specgram () method takes several parameters that customizes the spectrogram based on a given signal.
