WebApr 20, 2024 · A Butterworth filter design can be applied by using MATLAB. First, two random signals with different frequencies are generated and merged. The two signals have frequency of 40 Hz and 120 Hz respectively. These signals have frequency sampling (fs) of 1000 Hz. The following code is a MATLAB code to generate these signals.
WebMATLAB has amdemod (see MATLAB documentation) which can be used to recover suppressed carrier AM modulated signal. From the documentation, the demodulator uses a low-pass filter generated using [num,den] = butter (5,Fc*2/Fs). This can be a good start. In your simulation, the sampling frequency is 1000 Hz, which means the Nyquist frequency … WebJun 26, 2014 · This is a fair method to determine the coefficients for a Butterworth filter: Theme.
