Short-Time FFT
Nonparametric estimate of spectrum using short-time fast Fourier transform (STFT) method
Libraries:
DSP System Toolbox /
Transforms
Description
The Short-Time FFT block computes a nonparametric estimate of the spectrum. The block buffers, applies a window, and zero pads the input signal. The block then takes the FFT of the signal, transforming it into the frequency domain.
