eqfir(1)                       Scilab Function                       eqfir(1)
NAME
  eqfir - minimax approximation of FIR filter

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

PARAMETERS

  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

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

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