IIR数字滤波器的计算机设计方法

Automatic Designing Method of ⅡR Digital Filter by Computer

推导出了从原型低通模拟滤波器转换到不同类型的IIR数字滤波器的矩阵表示方法，实现了IIR数字滤波器的计算机自动设计，并编制了一套IIR数字滤波器设计软件．通过设计实例证明，简化了IIR数字滤波器的设计程序．

Deduces the matrix representations from original low-pass analogue filter to variousⅡR digital filters. This makes it possible to design ⅡR DF automatically by computer. A procedureof ⅡR DF design is programmed and a satisfying result is obtained based on some samples.
