Abstract
Circuit arrangement for generating a sawtooth voltage which has a substantially nominal frequency in the absence of synchronization pulses, whereby the changeover to direct synchronizability takes place as soon as a synchronization pulse comes into coincidence with the sawtooth flyback. In this way a phase change is avoided when the changeover is made. The changeover to nominal frequency occurs as soon as a pulse fails to occur within the natural period effective in case of direct synchronization. A threshold value circuit has an intermediate value which prevents synchronization by interference pulses occurring prematurely.
