Noun
lowpass (plural lowpasses)
(digital signal processing) An audio filter that discards higher frequencies while preserving lower ones.
A lowpass filter is also included, with - 24dB per octave attenuation, and controls for cutoff frequency, resonance, and envelope modulation parameters. Source: Internet
Resampling to 12000 (6K bandwidth) is selected by the LAME parameter -V 9.4 Likewise -V 9.2 selects 16000 sample rate and a resultant 8K lowpass filtering. Source: Internet
Note that the phase of the sine wave is different for the lowpass and the highpass cases, due to the phase distortion of the filters. Source: Internet
The accompanying figure shows a schematic of a waveform being filtered by a bandpass filter consisting of a highpass and a lowpass filter. Source: Internet
The algorithm used a loop gain of 0.98 with increasingly attenuating first order lowpass filters. Source: Internet
The filter can be a first-order lowpass filter (as pictured). Source: Internet
