ABSTRACT:
A delayed transition kinescope blanking pulse generator has a switch controlled by the deflection synchronizing pulses. The switch is coupled to a terminal of an energy storage means having a time constant. The switch changes the coupling of an energizing source to the energy storage means. A comparator coupled to the energy storage means and to a reference produces a blanking pulse having a transition the delay of which is determined by the time constant.
