- Figure 1. A digitally programmable potentiometer enables adjustment to this Schmitt trigger's upper and lower hysteresis limits, although the limits aren't independently programmable
- Figure 2. The transfer characteristic of the Figure 1 circuit illustrates the hysteresis curve, and the lower and upper limits
- Figure 3. Adding steering diodes D1 and D2, plus another potentiometer, allows independent programming of the upper and lower hysteresis limits
