AUTOMATIC CONTROL, STARTING, SYNCHRONISATION, OR STABILISATION OF GENERATORS OF ELECTRONIC OSCILLATIONS OR PULSES (of dynamo-electric generators Fulltext... Hierarchy... Expanded...H02P) [3]
H03L
Note(s)
This sub-class includes automatic control circuits for generators of electronic oscillations or pulses and also includes starting, synchronisation, or stabilisation circuits for generators where the type of generator is irrelevant or unspecified. Stabilisation or starting circuits specially adapted to only one specific type of generator are classified with the generator in the relevant sub-group of sub-classes Fulltext... Hierarchy... Expanded...H03B, Fulltext... Hierarchy... Expanded...H03K. [3]
The term "automatic control" includes only closed loop systems. [3]
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 (Fulltext... Hierarchy... Expanded...H03L 7/22 takes precedence) [3]

using more than one loop [3]

using a reference signal directly applied to the generator [3]

using energy levels of molecules, atoms, or subatomic particles as a frequency reference [3]
