Filter circuit arrangement having a plurality of cascaded FIR filters

摘要

The filter circuit arrangement provides the properties of an FIR filter of length N, with K (K>/=2) cascaded FIR-filter members. One FIR-filter member (5.K) is formed as an equalizer filter of length NA and the remaining FIR-filter members (5.1 to 5.(K-1)) are 1/M band filters of length Nk, so that whereinPk=Nk-2+537 [+E,fra 1/2+EE (Nk-1)]/Mk+540 .
