Might be wrong here, but I was understanding that it was a frequency and not a voltage since the data input was digital on or off only. The resistor would cause the leading edge to peak sooner and decrease off frequency and if it was actually a sine wave, tend to increase the waveform towards clamping which would be the same result.
If the off frquency goes below a target value it means one state probably rich, if it goes above it's lean. Easey peasey to do digitally.
