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 subclass covers:
automatic control circuits for generators of electronic oscillations or pulses; [3]
starting, synchronisation, or stabilisation circuits for generators where the type of generator is irrelevant or unspecified. [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]
H03L 7/22
· · ·
using more than one loop [3]
H03L 7/24
·
using a reference signal directly applied to the generator [3]
H03L 7/26
·
using energy levels of molecules, atoms, or subatomic particles as a frequency reference [3]
