WebBoth filters are preferably two phase filters. In operating the polyphase filter arrangement the loop gain at the unwanted "image" frequency can either be made much greater than unity thereby making the feed forward path insensitive to mismatching or be made much less than unity thereby making the feedback path insensitive to mismatching. 462 WebPolyphase Filter Partition Let N = L*M N = Filter Length M = Resampling Rate L = Subfilter Length Place filter coefficients columnwise into an M by L matrix.
