Abstract
A digital phase-locked loop (1) has a counter (4) which counts pulses from a voltage controlled oscillator (8). The counter (4) is latched periodically with a period which is determined by an input signal (I) to the counter (4). The latched value is supplied to a compensation unit (5) which deducts a value which approximately corresponds to half the count counted by the counter circuit (4) when the phase lock is locked correctly. The compensated counts are supplied from the output of the compensation unit (5) to an integrator (6) and counter (9) which applies a control signal to the voltage controlled oscillator (8) via a D/A converter.
