This module converts an Alternating Signal (AS) to a Digital Signal (DGS).

There are two outputs for each input – this is because the conversion is based on a threshold value (set by the knob).  When the signal is under the threshold, the left output goes high (outputs a 1), and when the signal is over the threshold, the right output goes high.

You can switch the orientation of under/over with the button, or by addressing the input under the button with a DGS.
