This MATLAB function returns the Short-Time Fourier Transform (STFT) of the input signal x.

Spectrogram Computation with Signal Processing Toolbox Signal Processing Toolbox™ provides three functions that compute the spectrogram of a nonstationary signal. Each of the functions …

The magnitude squared of the STFT is known as the spectrogram time-frequency representation of the signal. For more information about the spectrogram and how to compute it using Signal …

This MATLAB function returns the cross-spectrogram of the signals specified by x and y.

Time-Frequency Analysis Spectrogram, synchrosqueezing, reassignment, Wigner-Ville, time-frequency marginals, data-adaptive methods Signal Processing Toolbox™ provides functions …

When called with no output arguments, both pspectrum and spectrogram plot the spectrogram of the signal in decibels. Include the factor of 2 for one-sided spectrograms. Set the colormaps to …

Spectrograms are a two-dimensional representation of the power spectrum of a signal as this signal sweeps through time.

To display the time-dependent spectrum of a nonstationary signal, Signal Analyzer divides the signal into overlapping Kaiser-windowed segments and computes their short-time Fourier …

This example shows how the variable time-frequency resolution of the continuous wavelet transform can help you obtain a sharp time-frequency representation. The continuous wavelet …

This MATLAB function returns the mel spectrogram of the audio input at sample rate fs.
