Pulse generator employing plural monostable multivibrators providing variable width output

Claim 1

A TRANSISTORIZED FAST PULSE GENERATOR COMPRISING OSCILLATOR MEANS FOR SELECTIVELY GENERATING ONE OF A PLURALITY OF STABLE FREQUENCIES HAVING A SQUARE WAVEFORM, A FIRST DIFFERENTIATING CIRCUIT CONNECTED TO THE OUTPUT OF SAID OSCILLATOR MEANS FOR PROVIDING A NARROW PULSE CONTROL SIGNAL, A FIRST MONOSTABLE TRANSISTOR MULTIVIBRATOR CONNECTED TO SAID FIRST DIFFERENTIATING CIRCUIT SO AS TO BE TRIGGERED BY SAID NARROW PULSE CONTROL SIGNAL, MEANS WITHIN SAID FIRST MULTIVIBRATOR FOR SELECTIVELY VARYING THE DELAY TIME BETWEEN EACH APPLIED TRIGGER PULSE AND THE GENERATED OUTPUT PULSE, A SECOND DIFFERENTIATING CIRCUIT CONNECTED TO SAID FIRST MULTIVIBRATOR FOR CONVERTING THE OUTPUT THEREOF TO A NARROW CONTROL PULSE, A SECOND MONOSTABLE TRANSISTOR MULTIVIBRATOR CONNECTED TO SAID SECOND DIFFERENTIATING CIRCUIT SO AS TO BE TRIGGERED BY SAID NARROW CONTROL PULSE, MEANS WITHIN SAID SECOND MULTIVIBRATOR FOR SELECTIVELY VARYING THE WIDTH OF THE OUTPUT PULSES DERIVED THEREFROM, AND TRANSISTOR CONTROL MEANS CONNECTED TO SAID SECOND MULTIVIBRATOR FOR PROVIDING A PAIR OF OUTPUT SQUARE WAVE SIGNALS OF OPPOSITE POLARITY HAVING SELECTIVELY VARIABLE PULSE SPACING AND PULSE WIDTH.
