The FIR interpolation filter is implemented efficiently using a polyphase structure. To derive the polyphase structure, start with the transfer function of the FIR filter: H ( z) = b 0 + b 1 z − 1 + ... + b N z − N. N +1 is the length of the FIR filter. You can rearrange this equation as follows: WebPolyphase decimation-by-4 filter structure as a bank of FIR sub-filters.
