WebNov 15, 2024 · Upsample X16, Farrow filter, and then downsample by a factor of 16. Of course, both upsample and downsample filters will be implemented in the polyphase form to reduce the computational cost. Given that the output rate goes above and below the input rate, I need to use the Farrow for interpolation at times and decimation at other times. WebThe fractional delay for the Farrow filter is tunable and can be altered to lead a different magnitude response. You can see this by creating a set of filters that are copies of the …
