Signal reject circuit for monitoring mixed plural signals

Claim 1

A SIGNAL REJECT CIRCUIT COMPRISING IN COMBINATION, A MIXER-ATTENUATION MEANS HAVING INDIVIDUAL INPUT TERMINALS FOR RECEIVING A PLURALITY OF SIGNALS FROM A DYNAMIC SOURCE OF ELECTROMAGNETICALLY STORED SIGNALS REPRESENTING AN INSTANTANEOUS PATTERN VOLTAGE WAVEFORM, AND DELIVER A MIXED-ATTENUATED SIGNAL WHICH IS A FUNCTION OF THE HIGHEST MAGNITUDE OF SAID PLURALITY OF SIGNALS, ADDITIONAL ATTENUATION MEANS CONNECTED TO RECEIVE POWER AMPLIFIED SIGNALS AND DELIVER AN ADDITIONAL ATTENUATED SIGNAL, BUFFER-MIXER MEANS FOR RECEIVING BOTH SAID ATTENUATED SIGNALS AND FOR DELIVERING A MIXED SIGNAL WHICH IS EQUAL IN MAGNITUDE TO THE HIGHER OF SAID BOTH ATTENUATED SIGNALS, AND GATING MEANS ENABLED BY A PREDETERMINED SIGNAL AND CONNECTED TO RECEIVE SAID MIXED SIGNAL AND FOR DELIVERING A LINEAR GATING SIGNAL AT ITS OUTPUT, COMPARATOR MEANS CONNECTED TO RECEIVE SAID GATING SIGNAL AT ITS INPUT AND FOR ELECTRICALLY COMPARING THE AMPLITUDE OF SAID LINEAR GATING SIGNAL WITH A FIXED REFERENCE VOLTAGE AND FOR DELIVERING A TRIGGER SIGNAL WHEN SAID FIXED REFERENCE VOLTAGE IS EXCEEDED, SAID FIXED REFERENCE VOLTAGE BEING CHOSEN IN RELATION TO THE AMPLITUDE OF SAID MONITORED SIGNALS SO AS TO CAUSE A TRIGGER SIGNAL TO BE DELIVERED WHEN THE INSTANTANEOUS PEAK OF ONE OF SAID MONITORED SIGNALS EXCEEDS A DESIRED LEVEL, AND UNIVIBRATOR MEANS COUPLED TO SAID COMPARATOR MEANS FOR DELIVERING AN OUTPUT MONITORING SIGNAL OF FIXED TIME WIDTH UPON RECEIPT OF THE LEADING EDGE OF SAID TRIGGERING SIGNAL.
