WFILT_REMEZ Filters designed using Remez exchange algorithm
Usage: [h,g,a]=wfilt_remez(L,K,B)
Input parameters:
L : Length of the filters.
K : Degree of flatness (regularity) at z=-1.
B : Normalized transition bandwidth.
[h,g,a]=WFILT_REMEZ(L,K,B) calculates a set of wavelet filters.
Regularity, frequency selectivity, and length of the filters can be
controlled by K, B and L parameters respectivelly.
The filter desigh algorithm is based on a Remez algorithm and a
factorization of the complex cepstrum of the polynomial.
Examples:
---------
:
wfiltinfo('remez50:2:0.1');
