Magnitude Response

释义 Definition

“Magnitude response”指系统/滤波器的幅度响应:描述系统在不同频率下对输入信号幅度(增益)的影响,通常是频率响应的模值(|H(ω)| 或 |H(f)|)。在信号处理与控制中常与“phase response(相位响应)”一起讨论。

发音 Pronunciation (IPA)

/ˈmæɡnɪˌtuːd rɪˈspɑːns/

例句 Examples

The magnitude response of this low-pass filter is flat in the passband.
这个低通滤波器在通带内的幅度响应很平坦。

By examining the magnitude response, we can see how the system attenuates high-frequency noise while preserving the desired signal.
通过观察幅度响应,我们可以看出系统如何衰减高频噪声,同时保留所需信号。

词源 Etymology

“Magnitude”源自拉丁语 magnitudo,意为“大小、量值”;“response”源自拉丁语 respondere,意为“回答、响应”。组合在工程语境中表示“(系统对刺激的)量值层面的响应”,特指频域里增益随频率变化的曲线或函数。
