A Decimation Filter for Digital Down-Conversion
Ruzhang Li · 2011
Design of a decimation filter for digital down-conversion was presented in detail.The decimation filter,which was implemented by successively cascading a CIC filter,a CIC compensation filter and a half-band filter,achieved a decimation factor of 20.By utilizing equivalent transformation and polyphase decomposition of the decimation filter,both hardware cost and operating power of each sub-decimation filter were also reduced.
