Abstract

Circularly symmetric and diamond-shaped low-pass linear phase FIR filters are designed using coefficients comprising the sum or difference of two signed power-of-two (SPT) terms. A minimax error criterion is adopted in conjunction with an optimization process based on the use of genetic algorithms (GAs). The results presented are compared with those obtained using various other design methods, including simulated annealing, linear programming and simple rounding of an optimum (continuous) minimax solution. The filters designed using GAs exhibit superior performance to those designed using other methods.
