Butterworth analog High Pass Filter in Matlab

How to design a highpass filter designing with FDA tool using matlab

This simulation shows an RC Highpass Filter, which allows high-frequency signals to pass while attenuating low-frequency ones. The circuit has a 1 µF capacitor and a 1 kΩ resistor, giving a cutoff frequency of 159Hz. Signals above this frequency pass with less attenuation. The output waveform (red) shows that higher frequencies are preserved, while lower frequencies are suppressed. Additionally, the filter introduces phase shift, causing the output to lead the input phase by up to 90° at low fre
