Dithering as a factor in hysteresis elimination in rotating amplifiers

The aim of the present paper is to describe a theoretical approach for eliminating hysteresis effects in rotary amplifiers; this is achieved by employing a dithering technique. To obtain feasible mathematical relationships, the hysteresis curve is represented by a loop which is very close to the actual characteristic. In developing the analytical relationships, three operation ranges are defined, thus enabling computation of the output mean value as a function of the dc input component and the sinusoidal dithering signal.
