WIDTH AND PHASE CONTROL OF BLANKING PULSE

摘要

An apparatus comprises a source of a first signal synchronized to deflection, the first signal including a first portion representative of a retrace interval, means coupled to a first video signal and responsive to a second signal representative of the retrace interval for generating a second video signal having a blanking interval, and means responsive to a third signal representative of the blanking interval and to the first signal for generating the second signal so as to control the phase of the blanking interval relative to the retrace interval.
