Next, we will replace the clock line signal with the analog input voltage signal on
Channel 2. There is only one addition to make to the circuit.
As you adjust the potentiometer, watch the numeric value of the Channel 2 data signal in
the Debug Terminal, and the MEAN voltage in the CH2 Auto Measurements box. What
relationship do you see?
