Digital Filters – FIR & IIR
Here FIR filter and IIR filters are explained in detail along with applications. This course will be useful for students taking the ‘DSP’ course as well as for engineers who would like to implement filters practically. I will be regularly updating this course in near future.

IIR 濾波器設計
IIR 與 FIR 濾波器的比較 與 FIR 濾波器相比,將數字濾波器分為有限沖激響應(FIR)濾波器和無限沖激響應(IIR)濾波器。對于FIR濾波器,IIR卻擁有FIR所不具有的缺點,FIR濾波器與IIR濾波器的區別-基礎電子-維庫電子市 …

而另一方面,它的濾波器階數通常遠遠低于 FIR 濾波器。 雖然 IIR 濾波器具有非線性相位,沖激響應在有限時間內衰減為零,因而濾波器是穩定的系統。

While this is not explicitly turning an FIR filter into an IIR, the techniques will generally find an IIR solution unless some other constraints are applied. Some of the techniques are: Balanced Truncation is, in effect, a principal component analysis approach to reducing the order of a filter.
