Abstract

A simulated annealing optimization algorithm is used in the design of finite impulse response (FIR) filters and fifth-order LDI all-pole digital filters. Using simulated annealing, sin(x)/x precompensating scheme based on both the FIR and LDI structures is presented. The design process begins with a random set of finite precision coefficients for the filter, making no attempt to obtain a good initial starting coefficient. The use of simulated annealing allows the use of nonclassical transfer functions in the design of digital filters, i.e. it allows for the design of arbitrary magnitude response filters
