ABSTRACT:
Accurate phase switching of similar pulse trains having different phase position, in which a respectively selected pulse train determines a pulse train to be distributed by means of a phase locked loop, is achieved. Each pulse train is individually delayed so the phase position is roughly adjusted to zero with respect to the pulse train to be distributed. Each non-selected pulse train is continuously compared with the pulse train to be distributed. A phase error voltage is determined that corresponds to a phase difference still present as it would become effective as a control voltage in the phase locked loop. An oppositely equal correcting voltage is added to the phase error voltage to produce a sum, and the sum is made available as an output voltage. Switching to another pulse train is effected by maintaining the relevant correcting voltage at a momentary value and switching the associated output voltage into the phase locked loop as a control voltage in place of a previously used output voltage.
