WebMay 24, 2024 · The proposed design uses polyphase filters where each polyphase branch is considered as an FIR filter. The product-accumulation operations of the FIR filter are … WebAlgorithms. 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:
Web1-3, where the analog and digital resources of the circuit are shared by both the FIR DAC 30′ and the polyphase filter 40′. The reuse of data latched by the flip-flops 34 of the FIR DAC 30 ′ to provide the data for both the single bit DAC elements and the input to the decimation circuits 44 is advantageous as this data is generated at a rate corresponding to the …
