eqfir

eqfir — minimax approximation of FIR filter

Calling sequence

[hn]=eqfir(nf,bedge,des,wate)

`nf`	: number of output filter points desired
`bedge`	: Mx2 matrix giving a pair of edges for each band
`des`	: M-vector giving desired magnitude for each band
`wate`	: M-vector giving relative weight of error in each band
`hn`	: output of linear-phase FIR filter coefficients

Minimax approximation of multi-band, linear phase, FIR filter



hn=eqfir(33,[0 .2;.25 .35;.4 .5],[0 1 0],[1 1 1]);
[hm,fr]=frmag(hn,256);
plot(fr,hm),
