Abstract
Abstract A burst generator including a continuous wave oscillator, means to synchronize a pulse generator to the oscillator so that each pulse starts at a corresponding point on a cycle of the continuous wave, and a gating circuit actuated by the pulses to transmit repetitive bursts of oscillations, each starting at a corresponding point of a cycle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A synchronously pulsed burst generator comprising: a continuous wave oscillation generator; a counter circuit connected thereto to count a predetermined integral number of said oscillations; pulse generating means responsive to the output of said counter circuit to generate a pulse each time said predetermined integral number of oscillations has been counted; a gated circuit connected to said pulse generating means to be controlled thereby; and a connection from said continuous wave oscillation generator to said gated circuit, said gated circuit being actuated to transmit a burst of said oscillations at the occurrence of each of said pulses, the initial oscillation of eAch of said bursts beginning at the same phase.
Claim 2
Dependent Claim
110 words
A synchronously pulsed burst generator comprising: a continuous wave oscillation generator; a counter circuit connected thereto to count a predetermined integral number of said oscillations; pulse generating means responsive to the output of said counter circuit to generate a pulse each time said predetermined integral number of oscillations has been counted; a gated circuit connected to said pulse generating means to be controlled thereby; and a connection from said continuous wave oscillation generator to said gated circuit, said gated circuit being actuated to transmit a burst of said oscillations at the occurrence of each of said pulses, the initial oscillation of eAch of said bursts beginning at the same phase.
Claim 3
Dependent Claim
27 words
The invention as defined in claim 1 in which said counter circuit is a frequency divider and said continuous wave oscillation generator is a fixed frequency oscillator.
Claim 4
Dependent Claim
