Matlab里的low-pass filter Hi, 我想用matlab里的fir1来做一个low pass filter,我遇到的问题是我设计的两个cutoff frequency相差很大filter得出来的结果差不多,这两个filters是 b=fir1(10,[0.1]); 和 b=fir1(10,[0.01]); 上传的图里蓝色是原始数据 红色是第一个过滤掉10%的结果 绿色是第二个过滤掉1%的...
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,其中包括电子线路(如音频设备中使用的hi...
The Low-Pass Filter (Discrete or Continuous) block implements a low-pass filter in conformance with IEEE 421.5-2016[1]. In the standard, the filter is referred to as a Simple Time Constant. You can switch between continuous and discrete implementations of the integrator using the Sample time ...
y = lowpass：允许通过名称值参数自定义滤波选项，如阻带衰减、滤波器类型等。这提供了更灵活的滤波设置。返回滤波器对象：[y, d] = lowpass：除了返回滤波后的信号y，还返回用于过滤的digitalFilter对象d。这允许用户进一步检查和调整滤波器特性。绘图功能：lowpass：当无输出参数时，lowpass函数会绘制...
