Claim 1
Independent Claim
113 words
A FREQUENCY DIVIDER CIRCUIT COMPRISING A BLOCKING OSCILLATOR HAVING A PREDETERMINED OSCILLATING CYCLE, SAID BLOCKING OSCELLATOR INCLUDING A VOLTAGE FEEDBACK CIRCUIT CONNECTED TO FEED BACK A PORTION OF THE OUTPUT OF SAID BLOCKING OSCILLATOR TO INITIATE OSCILLATION IN SAID BLOCKING OSCILLATOR AT A PREDETERMINED VOLTAGE LEVEL, MEANS FOR APPLYING A SERIES OF TRIGGERING PULSES TO SAID VOLTAGE FEEDBACK CIRCUIT, A CONTINUOUSLY OPERATING VOLTAGE AMPLIFIER CONNECTED IN SERIES WITH SAID VOLTAGE FEEDBACK CIRCUIT, AND MEANS COACTING WITH SAID AMPLIFIER TO INCREASE THE AMPLIFICATION OF SAID VOLTAGE AMPLIFIER AT A PREDETERMINED TIME IN SAID OSCILLATING CYCLE TO INCREASE THE EFFECTIVE SLOPE OF THE VOLTAGE OF SAID FEEDBACK CIRCUIT IN THE REGION OF A TRIGGERING PULSE.
