ABSTRACT:
The present invention provides a method of and an apparatus for producing an output signal which is, relative to a periodic input signal, delayed by a predetermined phase angle phi. Initially, the phase angle phi between 0 and 2.pi. is divided by 2.pi. and multiplied by a predetermined positive integer number Z, whereby an integer phase number F between 0 and Z in obtained after rounding. Then, timing-pulse are, beginning with zero, counted between a first and a second input pulse, and an integer relative phase number P is obtained from the number N of the timing-pulses by multiplying by the phase number F, dividing by Z and rounding. Following the second input signal, the timing pulses are, beginning with zero, counted until the relative phase number P in reached. At last, an output pulse is emitted upon reaching the relative phase number P.
