WebDesign 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 ... WebMay 5, 2024 · High-pass filter. A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The amount of attenuation for each frequency depends on the filter design. A high-pass filter is usually modeled as a linear time ...
