coefficients of FIR low-pass

Calling Sequence




filter type where ft can take the values


for low-pass filter


for high-pass filter


for band-pass filter


for stop-band filter


integer (number of filter samples desired)


real (low frequency cut-off)


real (high frequency cut-off)


vector of filter coefficients


Get n coefficients of a FIR low-pass, high-pass, band-pass, or stop-band filter. For low and high-pass filters one cut-off frequency must be specified whose value is given in fl. For band-pass and stop-band filters two cut-off frequencies must be specified for which the lower value is in fl and the higher value is in fh
