ABSTRACT:
A processor (PR) is connected to the output of a phase comparator (PK) in a phase-locked loop. The processor (PR) calculates the phase shift of an input signal (f.sub.E) within an observation time span (for example, .DELTA.t=0-T) from the phase difference (.DELTA..phi.) at the output of the phase comparator (PK) and the parameters of the phase-locked loop (FT1, PK, FI, VCO, FT2).
