低通滤波器Low-pass filter 低通滤波器是容许低于截止频率的信号通过, 但高于截止频率的信号不能通过的电子滤波装置。 基本信息 介绍 低通滤波器 对于不同滤波器而言,每个频率的信号的强弱程度不同。当使用在音频应用时,它有时被称为高频剪切滤波器, 或高音消除滤波器。 低通滤波器概念有许多不同的形式,其中包括电...
定义 A low-pass filter (LPF) is a circuit that only passes signals below its cutoff frequency while attenuating all signals above it. It is the complement of a high-pass filter, which only passes signals above its cutoff frequency and attenuates all signals below it. What is a low-pass f...

Lowpassfilter是一种信号处理技术,用于滤除高频信号,只保留低频信号。它是一种滤波器,可以通过限制信号的频率范围来改变信号的频谱。低通滤波器通常用于去除噪音、平滑信号、降低信号的带宽等应用场景。 在云计算领域,低通滤波器可以应用于音频和视频处理、数据传输和通信等方面。例如,在音视频处理中,低通滤波器可以用于...
A low-pass filter, which is implemented with a Sallen–Key topology, withfc=15.9 kHz andQ= 0.5 这个电路是一个单位增益的电路,改变Sallen-Key 滤波器的增益同时就改变了滤波器的幅频特性和类型。 实际上Sallen-Key 滤波器就是增益为1的Butterworth 滤波器。
