Abstract

An overload circuit detects input signals that are too high or too low in amplitude and generates a holding signal of a predetermined duration. The holding signal is applied to a data selector which normally passes the input signal to a shift register/majority gate but switches to supply the output of the majority gate to the shift register when a holding signal is present. Thus, the output is maintained constant during the predetermined durations when a holding singnal is present.
