Programmable LPF
The low pass filter passes frequencies in the signal that are lower than the specified frequency, while
attenuating higher frequencies in the signal. With the programmable low pass filter you can set the
filter type and the slope between the frequency band that is passed and the band that is cutoff.
There are two types of programmable LPF components: mono channel and stereo channel. Mono
channel programmable LPFs have one input and one output. Stereo channel programmable LPFs
have two of each.
Double-click a component to display the component editor for it. The parameters are the same for
mono channel and stereo channel components.
