WebLow-pass filter: A ‘low-pass filter’, also referred to as a ‘high-cut filter’, allows only frequencies that are lower than a certain point to pass through. Simultaneously, it filters out the frequencies that are higher than that point. Pass filters have two controls. They are the filter’s cut-off frequency and the filter’s slope. WebApr 30, 2016 · Filter Slope. This is how steep the filter is (i.e., how sharply the filter attenuates sound below the cutoff frequency). Slope is expressed in dB/octave, indicating that the signal is reduced by a set number of … Web–High pass filter •Passes high frequencies, attenuates low frequencies –Band pass filter •Attenuates high and low frequencies, lets middle frequencies pass.
