A signal peak detection system is disclosed which in a preferred embodiment utilizes the initial actuation of one of a pair of regenerative threshold detectors by an input analog signal, the actuated detector providing threshold information to decision logic for initiating signal analysis processing at a suitable time prior to the occurrence of the signal peak. The system also includes storage units responsive to the respective states of the detectors, and gating circuits for providing an indication of the occurrence of an over-the-peak condition. Depending upon the nature of the input signal, such indication results either from the recovery of the detector initially actuated, or by the concurrent actuation of both detectors as reflected by the presence of output signals from the associated storage units. An over-the-peak output signal is generated by the system only when predetermined characteristics of the input signal have been validated by the decision logic.
