ABSTRACT:
A vertical deflection circuit including a Miller integrator and a Schmitt trigger circuit in combination to obtain a sawtooth wave signal at an output terminal of the Miller integrator circuit and a vertical deflection coil connected to the output terminal of the Miller integrator circuit to be supplied with the sawtooth wave signal therefrom in which the Schmitt trigger circuit is controlled by a vertical pulse signal for synchronization and the Miller integrator circuit is preferably controlled by a parabolic wave signal of the vertical scanning rate in order to compensate for or correct the non-linearity in the vertical deflection. The circuit configuration is well suited for being formed as an integrated circuit on a single semiconductor substrate.
