Low-Passive Filter

Low-Passive Filter

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.
