information

Split the input signal into a bank of parallel signals, one for each spectral band Contains: lowpass, 3 bandbass and highpass filter A Filter-Bank is a signal bandsplitter having the property that summing its output signals gives an allpass-filtered version of the filter-bank input signal. A more conventional term for this is an "allpass-complementary filter bank"
