【摘要】 本文介绍了一种新颖的计算机辅助设计滤波器的方法。现有的滤波器设计或是逼近其幅度特性、或是逼近其相位特性。而本文介绍的 Padé逼近法,可在无法写出网络函数解析表达式情况下,设计出能同时满足其特殊的幅度特性与相位特性的网络。更多还原

【Abstract】 A new computer-aided design method of filter is introduced in the paper. The general method of filter design approaches either amplitude response or phase response.The Padéapproach method described hero can be used to de- sign network that approaches both special amplitude and phase responses,in the absense of analytical expression of network function.更多还原
