Description

Class  H03L : AUTOMATIC CONTROL, STARTING, SYNCHRONISATION, OR STABILISATION OF GENERATORS OF ELECTRONIC OSCILLATIONS OR PULSES


Subclass 7/087: Automatic control of frequency or phase; Synchronisation (tuning of resonant circuits in general H03J; synchronising in digital communication systems, see the relevant groups in class H04) using a reference signal applied to a frequency- or phase-locked loop Details of the phase-locked loop concerning mainly the frequency- or phase-detection arrangement including the filtering or amplification of its output signal (H03L 7/1 takes precedence; frequency or phase detection comparison in general H03D 3/00, H03D 13/00) using at least two phase detectors or a frequency and phase detector in the loop
