The design of such filters does not only involve meeting a specific amplitude response but also imposes time domain constraints on the impulse response in order to ensure zero ISI. It is shown that genetic algorithm provides simple and effective technique for the design of finite precision filters with both frequency and time domain constraints. Furthermore, the algorithm computational time is low with respect to filter order and is independent of word length. Two filter design examples are included demonstrating the effectiveness of the design method.

Abstract

This paper investigates the use of genetic algorithm in the design of finite linear phase raised cosine FIR filters. The design of such filters does not only involve meeting a specific amplitude response but also imposes time domain constraints on the impulse response in order to ensure zero ISI. It is shown that genetic algorithm provides simple and effective technique for the design of finite precision filters with both frequency and time domain constraints. Furthermore, the algorithm computational time is low with respect to filter order and is independent of word length. Two filter design examples are included demonstrating the effectiveness of the design method.
