Tuning without displacement of reactive element, e.g. by varying permeability

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Continuous tuning > Details > Tuning without displacement of reactive element, e.g. by varying permeability

CPC:

Continuous tuning (H03J7/00, H03J9/00 take precedence; combination of continuous and discontinuous tuning other than for bandspreading H03J5/00) > Details > Tuning without displacement of reactive element, e.g. by varying permeability

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
