WebMany digital signal processing systems require linear phase filtering. Digital linear phase filters designed by either the window design method [1] or the optimal filter design method [1] are generally implemented by the direct convolution method which uses the filter’s impulse response as filter coefficients. If a linear phase filter has a finite impulse … http://www.dspguide.com/ch10/2.htm
