Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
105 words
A CIRCUIT FOR SENSING PEAK AMPLITUDE OF A SIGNAL COMPRISING A FIRST TIME DELAY CIRCUIT HAVING A LONG TIME CONSTANT AND A SECOND TIME DELAY CIRCUIT HAVING A SHORT TIME CONSTANT RELATIVE TO THE TIME CONSTANT OF THE FIRST TIME DELAY CIRCUIT, MEANS FOR APPLYING THE SIGNAL TO THE TIME DELAY CIRCUITS, AND SWITCHING MEANS CONNECTED BETWEEN THE TIME DELAY CIRCUITS AND RENDERED CONDUCTING UPON DISCHARGE OF THE SECOND TIME DELAY CIRCUIT IMMEDIATELY AFTER THE SIGNAL PASSES PEAK AMPLITUDE AND MEANS CONNECTED IN THE SWITCHING CIRCUIT AND RESPONSIVE TO CURRENT FLOW IN THE CIRCUIT FOR PROVIDING AN OUTPUT IMMEDIATELY AFTER THE SIGNAL PASSES PEAK AMPLITUDE.
