ABSTRACT:
A performance monitor for determining the error density of a digitally transmitted signal in which the magnitude of a d-c offset voltage applied to one regenerator is controlled in a feedback loop so as to maintain a constant error rate between the output of it and another regenerator; the magnitude of the voltage being a measure of the degradation of the received signal and hence its error density.
