WebFIR filter design using the window method. This function computes the coefficients of a finite impulse response filter. The filter will have linear phase; it will be Type I if numtaps is odd and Type II if numtaps is even. WebThus, the Hann window as returned by Matlab hanning function reaches zero one sample beyond the endpoints to the left and right. The minus sign, which differs from , serves to make the window causal instead of zero phase. The Matlab Signal Processing Toolbox also includes a hann function which is defined to include the zeros at the window ...
