Butterworth filter (巴特沃斯濾波器) | 大學教師學術專長資料庫

巴特沃斯濾波器（英語：Butterworth filter）是一種通頻帶（英語：passband）之頻率響應曲線平坦無漣波的訊號處理濾波器（英語：Filter (signal processing)）。

1. 利用運算放大器提出適當的訊號增益，使訊號通過濾波器不會衰減。 2. 不使用電感，使濾波器可製成體積小的積體電路。 3. 利用運算放大器的高輸入阻抗與低輸入阻抗，使 ...

The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband.

In the above example, we have designed a Butterworth filter with a cutoff frequency of 1000 Hz. The plot is the magnitude frequency response of the filter.

巴特沃斯濾波器是一種訊號處理濾波器，其設計目的是在通帶內具有盡可能平坦的頻率響應。這也稱為最大平坦幅度濾波器。 1930 年，英國工程師兼物理學家Stephen Butterworth ...
