Pulse generator employing bipolar-signal gated bistable amplifiers to produce unipolar, shaped output pulses

Claim 1

THE IMPROVEMENT OF A SIGNAL PROCESSING CIRCUIT OF GENERATING AN UNIPOLAR SIGNAL OF CONTROLLED PULSE WIDTH COMPRISING A SOURCE OF BIPOLAR INPUT SIGNALS, A PAIR OF PULSE FORMING SIGNAL CHANNELS COUPLED TO SAID SOURCE OF INPUT SIGNALS, EACH OF SAID SIGNAL CHANNELS COMPRISING A GATE CIRCUIT IN SERIES WITH A SWITCHING AMPLIFIER STAGE, SAID SWITCHING AMPLIFIER STAGE NORMALLY BEING HELD IN A NON-CONDUCTING CONDITION BY THE OPEN CONDITION OF ITS ASSOCIATED GATE CIRCUIT, EACH OF SAID GATE CIRCUITS BEING CLOSED UPON RECEIPT OF A SIGNAL OF A GIVEN POLARITY FROM SAID SOURCE TO SWITCH THE SWITCHING AMPLIFIERS TO A CONDUCTING CONDITION TO PROVIDE A SHAPED SIGNAL PULSE IN EACH SIGNAL CHANNEL AT THE OUTPUT OF EACH AMPLIFIER, STATIC DELAY MEANS HAVING A FIXED PREDETERMINED DELAY CONNECTED TO THE OUTPUT OF ONE OF SAID SIGNAL CHANNEL APPLIFIER STAGES, AND OUTPUT GATE MEANS ARRANGED TO BE RESPONSIVE TO THE SIMULTANEOUS PRESENCE OF OUTPUT SIGNALS OF THE SAME POLARITY IN BOTH SIGNAL CHANNELS FOR PROVIDING A UNIPOLAR SIGNAL PULSE OF CONTROLLED PULSE WIDTH, SAID CONTROLLED PULSE WIDTH BEING DETERMINED BY THE DELAY PERIOD OF SAID STATIC DELAY MEANS.
