View the Spectrogram Using Spectrum Analyzer - MATLAB
Spectrograms are a two-dimensional representation of the power spectrum of a signal as this signal sweeps through time.
Spectrogram Computation in Signal Analyzer - MATLAB
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 …
pspectrum - Analyze signals in the frequency and time
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 …
Practical Introduction to Time-Frequency Analysis - MATLAB
The spectrogram with default parameter values shows four coarse time-frequency ridges. Reduce the frequency resolution value to 3 kHz to get more details on the frequency variation of each …
Find and Track Ridges Using Reassigned Spectrogram - MATLAB
Use the reassigned spectrogram in Signal Analyzer to sharpen the time and frequency localization of spectrograms.
