Design high-pass filters using MATLAB. A high-pass filter attenuates signals below a cutoff frequency (the stopband) and allows signals above the cutoff frequency (the passband). The amount of attenuation depends on the design of the filter. High-pass filters are often used to clean up low-frequency noise, remove humming sounds in audio signals. We can use MATLAB for further signal processing. After the signal comes into the MATLAB using Arduino we can use another Low pass filter to achieve better results. We can also reduce all of the extra noise that is still present in the circuit by using another Notch filter in the MATLAB IIR Filters(infinite impulse response filter) High-pass and Low-pass; Now, lets' design this filter in MATLAB's simulink.
