H03L7/20 - CPC Classification

Classification description:

Automatic control of frequency or phase; Synchronisation using a reference signal applied to a frequency- or phase-locked loop; Indirect frequency synthesis, i.e. generating a desired one of a number of predetermined frequencies using a frequency- or phase-locked loop using a harmonic phase-locked loop, i.e. a loop which can be locked to one of a number of harmonically related frequencies applied to it
