Abstract
A field deflection circuit in a picture display device including a sawtooth generator for generating an essentially sawtooth-shaped voltage. The circuit is provided with a storage element in which information is stored under the influence of applied clock pulses. Per field period the number of times when the content of the storage element is changed is reduced to a predetermined number, e.g. because a number of clock pulses is omitted. The clock pulses applied to the sawtooth generator are then distributed as regularly as possible.
