Burst gate pulse generating circuit.

摘要

A burst gate pulse generating circuit includes first circuit (10) for generating a first voltage increasing at a predetermined time constant in synchronism with the leading edge of a pulse contained in a sync signal applied thereto, second circuit (20) for stopping the first voltage generating operation by the first circuit (10) when the trailing edge of the pulse contained in the sync signal arrives at the first circuit (10) before the first voltage reaches a fixed second voltage, and third circuit (30) for generating a train of burst gate pulses through the comparison of the first voltage derived from the first circuit (10) with fixed second and third voltages which are larger than the second voltage, and different from each other.
