Abstract
Abstract A system for generating a pulse train whose constituent pulses occur synchronously with a reference transition of a highfrequency oscillator, which may be easily extended to a system for generating a plurality of such pulse trains, and includes a frequency divider circuit for generating pulses whose frequency is a percentage of the frequency of the oscillator, a delay circuit for delaying the pulse output of the frequency divider circuit, and a gated pulse generator for generating the constituent pulses of the pulse train whenever enabled by the output from the delay circuit and triggered by the reference transition. The timing of the constituent pulses may be further controlled by a second delay circuit at the output of the pulsegenerating gate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
A system for generating a pulse train whose constituent pulses occur synchronously with predetermined reference transitions of a reference source comprising: a. timing means driven by said source for generating pulses whose periods equal a predetermined number of periods of said source; b. pulse-generating means for generating said constituent pulses of said pulse train; c. delay means connected to said timing means for delaying said pulses generated by said timing means; d. first interconnection means coupled between said pulsegenerating means and said delay means for enabling said pulsegenerating means with said pulses generated by said timing means and delayed by said delay means; and e. second interconnection means coupled between said pulsegenerating means and said reference source for triggering said pulse-generating means with said reference transitions, whereby said constituent pulses are generated by said pulse-generating means whenever enabled by said delay means and triggered by said reference transitions.
Claim 2
Independent Claim
148 words
A system for generating a pulse train whose constituent pulses occur synchronously with predetermined reference transitions of a reference source comprising: a. timing means driven by said source for generating pulses whose periods equal a predetermined number of periods of said source; b. pulse-generating means for generating said constituent pulses of said pulse train; c. delay means connected to said timing means for delaying said pulses generated by said timing means; d. first interconnection means coupled between said pulsegenerating means and said delay means for enabling said pulsegenerating means with said pulses generated by said timing means and delayed by said delay means; and e. second interconnection means coupled between said pulsegenerating means and said reference source for triggering said pulse-generating means with said reference transitions, whereby said constituent pulses are generated by said pulse-generating means whenever enabled by said delay means and triggered by said reference transitions.
Claim 3
Dependent Claim
12 words
The system of claim 1 wherein said source comprises a sinusoidal oscillator.
Claim 4
Dependent Claim
31 words
The system of claim 1 further comprising: a. a plurality of said pulse-generating means; b. a plurality of said delay means, whereby a plurality of said pulse trains may be generated.
Claim 5
Dependent Claim
39 words
The system of claim 3 further comprising second delay means connected to the output of said pulse-generating means, whereby the timing of said constituent pulses may be further controlled within time increments smaller than the period of said source.
