Lowpass FIR filter coefficients

A vector of filter coefficients (descending powers of z) to be shared by all the

lowpass filters in the filter bank.

Highpass FIR filter coefficients

A vector of filter coefficients (descending powers of z) to be shared by all the

highpass filters in the filter bank.

Number of levels

The number of filter bank levels. An n-level asymmetric structure has n+1

outputs; an n-level symmetric structure has 2

outputs.
