【Abstract】 The IIR filter design, which is in frequency least squares and ∞ norm mix criterion,is put forward, and the method to resolve it based on genetic algorithms is obtained. This new method avoids the disadvantage of other traditional techniques and the characters of designed filter with it are ideal. The given example shows this method is better than others.更多还原
