b = remez (n, f, a) ¶b = remez (n, f, a, w) ¶b = remez (n, f, a, w, ftype) ¶b = remez (n, f, a, w, ftype, griddensity) ¶Parks-McClellan optimal FIR filter design.
gives the filter order, where the generated filter length taps is n+1
gives frequency at the band edges [b1 e1 b2 e2 b3 e3 …]
gives amplitude at the band edges [a(b1) a(e1) a(b2) a(e2) …]
gives weighting applied to each band
is "bandpass", "hilbert" or "differentiator"
determines how accurately the filter will be constructed. The minimum value is 16, but higher numbers are slower to compute.
Frequency is in the range (0, 1), with 1 being the Nyquist frequency.
