DIFF Subgroup
H03B 7/02

with frequency-determining element comprising lumped inductance and capacitance

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Generation of oscillations using active element having a negative resistance between two of its electrodes > with frequency-determining element comprising lumped inductance and capacitance

CPC:

Generation of oscillations using active element having a negative resistance between two of its electrodes (H03B9/00 takes precedence) > with frequency-determining element comprising lumped inductance and capacitance

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
