Kaiser FIR filter design
Compute FIR filter for use with a quasi-perfect reconstruction polyphase-network filter bank.
qp_kaiser(nb, at, linear = FALSE)
nb |
number of frequency bands, specified as a scalar |
at |
attenuation (in dB) in the stop band. |
linear |
logical, indicating linear scaling. If FALSE (default), the Kaiser window is multiplied by the ideal impulse response h(n) = a sinc(an) and converted to its minimum-phase version by means of a Hilbert transform. |
The FIR filter coefficients, of class Ma
