I am looking for a circuit that allows the user to adjust the delta (= hysteresis window) between thresholds using 1 pot. and offset the thresholds using another.
For example - Using one pot. the user sets the window to 0.4V & using the second pot. the user sets the low threshold to 3.2V which means the high threshold is going to be 3.6V (3.2 + 0.4).
