Automatic Designing Method of ⅡR Digital Filter by Computer
-
摘要: 推導出了從原型低通模擬濾波器轉換到不同類型的IIR數字濾波器的矩陣表示方法,實現了IIR數字濾波器的計算機自動設計,并編制了一套IIR數字濾波器設計軟件.通過設計實例證明,簡化了IIR數字濾波器的設計程序.Abstract: Deduces the matrix representations from original low-pass analogue filter to various ⅡR digital filters. This makes it possible to design ⅡR DF automatically by computer. A procedure of ⅡR DF design is programmed and a satisfying result is obtained based on some samples.
