Abstract
It is the object to create a vertical deflection circuit which is suitable, in particular, for a symmetric deflection with a sinusoidal deflection current and a free-running horizontal deflection circuit not synchronised by the input signal. A vertical pulse derived from the received signal and a horizontal pulse (H*) derived from the horizontal deflection circuit are applied to the synchronising inputs of the vertical deflection circuit in such a manner that the vertical deflection in each case begins with the first horizontal pulse following an edge of the vertical pulse (V) derived from the received signal and ends in a wait position preceding the next vertical pulse (V). Suitable, in particular, for television receivers with a symmetric free-running horizontal deflection not synchronised by the input signal.
