hystereseband
Hystereseband, or hysteresis band, is the input range over which a system that exhibits hysteresis maintains its current state. In devices with two stable states, the output remains unchanged as the input changes within this band until a higher (or lower) threshold is reached to trigger a state transition. The width of the band is the difference between the upper and lower switching points.
In electronic circuits, the band is created by positive feedback, most commonly in Schmitt triggers or relays.
Hysteresis bands are used in thermostats, position sensors, motor controllers, and power electronics to prevent rapid
