WebWarning: Odd order symmetric FIR filters must have a gain of zero at the Nyquist frequency. The order is being increased by one. Alternatively, you can pass a trailing 'h' argument, as in firpm(N,F,A,W,'h'), to design a type 4 linear phase filter. Band-pass filter WebThe magnitude plot indicates that the moving-average filter passes low frequencies with a gain near 1 and attenuates high frequencies, and is thus a crude low-pass filter. The phase plot is linear except for discontinuities at the two frequencies where the magnitude goes to zero. The size of the discontinuities is π, representing a sign reversal.
