H03J 3/30 Arrangements for ensuring tracking with variable inductors
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Continuous tuning > of more than one resonant circuit simultaneously, the tuning frequencies of the circuits having a substantially constant difference throughout the tuning range > Arrangements for ensuring tracking with variable inductors
CPC:
Continuous tuning (H03J7/00, H03J9/00 take precedence; combination of continuous and discontinuous tuning other than for bandspreading H03J5/00) > of more than one resonant circuit simultaneously, the tuning frequencies of the circuits having a substantially constant difference throughout the tuning range > Arrangements for ensuring tracking with variable inductors
No child classifications to compare. This is a leaf node in both IPC and CPC.
