如何在通过8Hz至35Hz的matlab中实现椭圆滤波器? [英] How to implement elliptic filters in matlab that passes 8Hz to 35Hz?

问题描述

我有一个表示为矩阵的采样信号，需要对其进行滤波以仅允许8-35 Hz.结果也应该是矩阵！

解决方案

使用"fdatool"创建过滤器.选择响应类型Bandpass和设计方法IIR - Elliptic.现在，您可以填写频率/幅度规格，然后通过幅度"检查幅度/相位响应.如果满意，请按File > Generate Matlab Code并选择Data Filtering Function.

I have a sampled signal represented as matrix which needs to be filtered to allow only 8-35 Hz. The result also should be a matrix !!

解决方案

Use the 'fdatool' to create your filter. Select the Response type Bandpass and the design methode IIR - Elliptic. Now you can fill in your freqency/magnitude specifications and Magnitude check the Magnitude/Phase response. When you are satisfied hit File > Generate Matlab Code and select Data Filtering Function.
