Hysteresis

The electronics a hysteresis is the name for a behavior in which a circuit responds with a delay to an event.

Illustration Hysteresis.

You find a hysteresis in many circuits. However, the effect is often very small and difficult to observe. With targeted changes you are able to enhance the hysteresis and exploit it to your advantage...
