Digital Filter Design of IIR Filters using Real Valued Genetic Algorithm
Blekinge Institute of Technology, Department of Telecommunications and Signal Processing2003 (English)Conference paper (Refereed) Published
This paper presents a new paradigm for infinite impulse response (IIR) filter design using genetic algorithms (GA). By encode or transform the filter design problem into the z-plane the GA optimization procedure will be simplified. Additionally, given the z-plane encoding new mutation techniques are introduced, with the intention to locate promising regions in the search space. With proper design of the fitness function, the proposed algorithm can be used to evolve both full precision or quantized filter structures.
