Polyphase Decimation Filter
Description
The primary reason for using Polyphase decimation is to decrease the sampling rate at the output so that
another system operating at a lower sampling rate can use the filtered signal. Another reason is reducing the
processing cost. In any case, the decimation filter performs low-pass filtering and down sampling.
Interface
Parameters or Generics
Decimation CoreFIR RTL has parameters (Verilog) or generics (VHDL), which are described in Table 13 . All
parameters and generics are positive integer types. The table shows the superset of the parameters used by
all FIR filter types, while indicating which parameters the Polyphase Decimation type does not utilize.
