WebA high pass filter (HPF) is a filter that tempers all the frequencies that are below the certain cutoff frequency and allows the frequencies that are above to pass. This filter can appear at many stages of the signal path. Such states are the microphone, the amplifier, the equalizer, or the plugin, for example. In this case, the slope of filter tempering tends to be quantified … WebApr 30, 2016 · Filter Slope.
