Pulse amplitude comparator

Claim 1

A PULSE AMPLITUDE COMPARATOR FOR COMPARING A PAIR OF INPUT SIGNALS WHICH COMPRISES A PAIR OF TRANSISTOR AMPLIFIERS HAVING RESPECTIVE INPUT AND OUTPUT CIRCUITS, MEANS FOR SUPPLYING INPUT SIGNALS TO SAID TRANSISTOR INPUT CIRCUITS, RESPECTIVELY, INCLUDING THE DIRECT-CURRENT COMPONENTS THEREOF, A THIRD TRANSISTOR HAVING A COLLECTOR OUTPUT CIRCUIT, DIRECT-CURRENT CONNECTIONS FROM THE OUTPUT CIRCUITS OF SAID PAIR OF TRANSISTOR AMPLIFIERS TO THE BASE AND EMITTER OF SAID THIRD TRANSISTOR, RESPECTIVELY, FOR APPLYING AMPLIFIED INPUT PULSE SIGNALS IN LIKE POLARITY THERETO INCLUDING THE RESPECTIVE DIRECT-CURRENT COMPONENTS THEREOF AND PRODUCING A RESPONSE IN SAID COLLECTOR OUTPUT CIRCUIT WHEN THE AMPLITUDES OF AMPLIFIED INPUT PULSES SIMULTANEOUSLY APPLIED TO SAID BASE AND EMITTER DIFFER IN A PREDETERMINED DIRECTION, AND A NONOSTABLE OSCILLATOR CONNECTED TO BE TRIGGERED BY RESPONSES IN SAID COLLECTOR OUTPUT CIRCUIT FOR YIELDING OUTPUT SIGNALS OF SUBSTANTIALLY CONSTANT AMPLITUDE FOR CORRESPONDING SIMULTANEOUS OCCURRENCES OF PULSES IN SAID INPUT CIRCUITS WHICH DIFFER BY A PREDETERMINED AMOUNT IN ONE DIRECTION.
