It can be defined as how close any …

NettetHysteresis. Hysteresis is the difference between two separate measurements taken at the same point, the first is taken during a series of increasing measurement values, and the other during during a series of decreasing measurement values. The hysteresis is caused by the natural reluctance of a material to return to an original state after ...
