Abstract

An arrangement for automatic switching of the regulating speed of a phase regulating circuit, in which the regulating speed is not switched abruptly. The regulating speed is, instead, switched either discontinuously or continuously, so that it does not attain a high level before the midpoint of the synchronizing pulse. The regulating speed is increased within a synchronizing window to an increasing extent up to the midpoint of the window, whereas the regulating speed decreases to a decreasing extent from that midpoint. The regulating speed of the phase regulating circuit is associated with the horizontal deflection in a television receiver, where interference in the vicinity of the synchronizing pulse has a detrimental effect, particularly near the edges.
