MATLAB中的低通滤波器（Low Pass Filter）提供了多种实现方式。首先，从基础的lowpass函数开始，它接受一维信号x，截止频率fpass和采样频率fs作为参数。例如，对于两个不同频率（50Hz和250Hz）的信号，通过lowpass函数以150Hz为截止频率处理，但需注意，设置steepness（默认0.85）过近1可能导致假峰出现。...

MATLAB中的lowpass函数用于对输入信号进行低通滤波，其主要用法和功能如下：基本语法：y = lowpass：使用归一化通带频率wpass对输入信号x进行低通滤波，滤波器具有60分贝的阻带衰减，并自动补偿延迟。y = lowpass：在指定采样率fs下，使用赫兹为单位的通带频率fpass对输入信号x进行滤波。y = lowpass：对...
