WebFeb 22, 2013 · Polyphase filter is a combination of filtering plus down sampling. It uses an Fir filter for filtering and then down sample it with the given decimation factor. I understand with filtering it's the convolution of the input signal with the impulse response, so you just have to call the convolution function.
