# find_freq

### 呼び出し手順

`[m]=find_freq(epsilon,A,n)`

epsilon

A

n

フィルタ次数

m

### 説明

`m1=(epsilon*epsilon)/(A*A-1)`として, `n=K(1-m1)K(m)/(K(m1)K(1-m))`となるような mを探します.

`m= omegar^2/omegac^2`の場合, パラメータ `epsilon,A,omegac,omegar` および `n`は 楕円フィルタの雛形の定義と互換になります. ここで, `K=%k(m)` は,パラメータ`m`を指定した 完全楕円積分です.

### 参照

• %k — ヤコビの完全楕円積分
