WebApr 10, 2024 · Image-rejection filter: this filter “interpolates” the response of the shaping filter, hence the name of the technique (it is a normal FIR filter). What’s common between the Interpolated FIR and the Polyphase filter is the filter structure of the Shaping filter and the Transposed Polyphase, derived in the previous section. WebPolyphase decomposition of an FIR filter is a power efficient technique as it allows operation of subfilters at lower data rates and also computation of only useful output …

WebThe Finite Impulse Response (FIR) Filter is one of the most ubiquitous and fundamental building blocks in DSP systems. Although its algorithm is extremely simple, the variants … A polyphase quadrature filter, or PQF, is a filter bank which splits an input signal into a given number N (mostly a power of 2) of equidistant sub-bands. These sub-bands are subsampled by a factor of N, so they are critically sampled. An important application of the polyphase filters (of FIR type) concerns the filtering and decimation of large band (and so high sample rate) input signals, e.g. coming from a high rate ADC, which can not be directly processed by an FPGA or in some ca…

A little reading on Polyphase FIR filters indicated me that the total number of taps *per every sub-filter* in a polyphase structure should be ceil(1005/M1) = 50 and so I would have M1=20 such filters.
