WebThis representation is known as polyphase representation and is used to implement efficient filter banks : \[ X(z)=\sum_{i=0}^{M-1} P_{i}(z^{M}) z^{-i} \] ... A filter bank is a system in which two or more filters are used together to analyze and process a given signal. ... the high pass filter can be obtained by alternating flip method, ie ... 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. One application of a filter bank is a graphic equalizer, which can attenuate the components differently and recombine them into a modified version of the original signal.
