What is a low-pass filter in MATLAB?
- Low-Pass Filter Design low-pass filters using MATLAB A low-pass filter is a filter that allows signals below a cutoff frequency (known as the passband) and attenuates signals above the cutoff frequency (known as the stopband).

How to design a filter in MATLAB?
- In practical life, we use LRC circuits to design these filters. In MATLAB, we can design them in different ways. We can see the response of any filter by designing an LRC circuit in MATLAB Simulink, or we can just give a signal to a built-in filter in Simulink and use the scope to see it.
How do I know if a signal is filtered in MATLAB?
- The waveforms show the filtration clearly but we can also listen to the music to get the difference. To listen to the music in Matlab, we execute the sound command sound (xn, fs) for the noisy signal in the command window. We also do the same for the filtered signal sound (y, Fs).
