What does a filterbank do?
In signal processing, a filter bank (or filterbank) is an array of bandpass filters that separates the input signal into multiple components, each one carrying a single frequency sub-band of the original signal.
What is uniform DFT filter bank?
DFT Filter Banks is Fourier transform filter bank which can be constructed using length M FIR bandpass filters where each bandpass filter is implemented as a demodulator followed by a running-sum lowpass filter.
What is auditory filter bank?
Auditory filter banks are non-uniform bandpass filter banks designed to imitate the frequency resolution of human hearing [308,180,87,208,255]. Classical auditory filter banks include constant-Q filter banks such as the widely used third-octave filter bank.
