ABSTRACT:
Method and filters for reducing the number of circuit components and/or the operating speed of the components of a filter used to shape digital transmit symbols for conversion to analog modulation communication systems. A digital signal is processed using M circuit stages. The stages multiply a delayed digital signal and a further delayed digital signal with a corresponding filter coefficient. The output signals of the stages are multiplexed to provide shaped digital transmit symbols. The stages are configured to reduce the number of circuit components and/or operating speed.
