Solid state circuit averages multiple signals and rejects those varying significantly from the average
Average and reject logic control system provides an average of the output signals of transducers measuring critical parameters. It uses a circuit that compares each signal against an average, rejects any signal that departs significantly from the average, and supplies an average of the acceptable signals.

Circuit measures hysteresis loop areas at 30 Hz
Analog circuit measures hysteresis loop areas as a function of time during fatigue testing of specimens subjected to sinusoidal tension-compression stresses at a frequency of Hz. When the sinusoidal stress signal is multiplied by the strain signal, the dc signal is proportional to hysteresis loop area.
