What is analysis filter bank?
The analysis filter bank divides an input signal to different subbands with different frequency spectra. The synthesis part reassembles the different subband signals and generates a reconstructed signal. Two of the basic building blocks are the decimator and expander.
How many types of filter banks are there?
There are two main types of filter banks. An analysis filter bank and a synthesis filter bank.
What are filter banks used for?
A digital filter bank is a set of digital band pass filters that is used to analyze a given input signal by separating it into multiple signals with non-overlapping frequency content. They can also be used to synthesize or construct multiple input signals of non-overlapping frequency content into a single output.
What is synthesis filter bank?
The synthesis filter bank, also known as the channel synthesizer, consists of a set of parallel bandpass filters that merge multiple input narrowband signals, y0[m], y1[m], y2[m], … , yM-1[m] into a single broadband signal, v[n]. The input narrowband signals are in the baseband.
