Frequency-Domain Finite Impulse
Response
Filter Bank
The finite impulse response (FIR) filter is one of the basic operations in
signal processing. This kernel implements a set of M FIR filters. Each FIR filter
m, m ∈ {0, 1, ..., M-1 }, has a set of impulse response coefficients wm[k], k
∈ { 0 ... K-1 }. If the length of the input vector is N,
the output of filter m, ym, is the convolution of wm with the input
xm:
