【Abstract】 The design of FIR digital filters could be changed into the parameters of FIR digital filter parameters.Particle Swarm Optimization and Quantum-behaved Particle Swarm Optimization are described.The optimization algorithms are used to search the whole parameters space and thus obtain the parameter optimization.Simulation indicates that these design methods,according to the requirement of target characteristics of the FIR filter,are completely effective and practicable.更多还原
