Short-Time Fourier Transform Using Cascade Filter Structures

A wide class of short-time Fourier transforms (STFT's), or spectrograms, can be obtained by applying an infinite-length analysis window, corresponding to an impulse response of an IIR filter, at every data sample and then taking the Fourier transform. The use of the cascade form realization of the a...
