The dS-LPF is a passive 20kHz low-pass filter in 2 or 4-channel configurations designed
primarily for measuring digital power amplifiers.

The Passive Low-pass Filter is intended to aid measurement of switching (’Class D’, or
‘PWM’) power amplifiers where the presence of shaped and switching noise outside the
audio band can adversely affect the Analogue Inputs of the dScope or other audio analyzer.
