Peak detecting circuit

Claim 1

APPARATUS FOR INDICATING THE OCCURRENCE OF A PEAK LEVEL OF A VOLTAGE SIGNAL COMPRISING: A PAIR OF CURRENT CONDUCTING DEVICES HAVING INPUTS COMMONLY CONNECTED FOR RECEIVING SAID VOLTAGE SIGNAL; A CAPACITOR COMMONLY CONNECTED TO THE OUTPUTS OF SAID CURRENT CONDUCTING DEVICES WHEREBY ONE CURRENT CONDUCTING DEVICE CHARGES SAID CAPACITOR AS SAID VOLTAGE SIGNAL HAS A POSITIVE EXCURSION AND THE OTHER CURRENT CONDUCTING DEVICE DISCHARGES SAID CAPACITOR DURING THE NEGATIVE EXCURSION OF SAID VOLTAGE SIGNAL; A PEAK INDICATING CURRENT CONDUCTING DEVICE HAVING AN INPUT CONNECTED TO RECEIVE SAID VOLTAGE LEVEL AND AN OUTPUT FOR INDICATING THE TIME THE PEAK LEGEL OF SAID VOLTAGE SIGNAL OCCURS, SAID PEAK INDICATING CURRENT CONDUCTING DEVICE PROVIDES AN INDICATION OF A VOLTAGE PEAK WHEN IT SWITCHES FROM A STATE OF CONDUCTION TO A NON-CONDUCTING STATE; AND A UNIDIRECTIONAL CURRENT CONDUCTING DEVICE CONNECTED BETWEEN SAID CAPACITOR AND SAID PEAK INDICATING CURRENT DEVICE TO PREVENT SAID PEAK INDICATING CURRENT CONDUCTING DEVICE FROM CHARGING SAID CAPACITOR SO THAT THE CURRENT CONDUCTED BY SAID PEAK INDICATING CURRENT IS INDEPENDENT OF THE STATE OF SAID CAPACITOR AND TO PERMIT THE CAPACITOR OF FACILITATE TURN OFF OF SAID PEAK INDICATING CURRENT CONDUCTING DEVICE JUST AFTER SAID VOLTAGE SIGNAL REACHES A PEAK.
