DIFF Subgroup
H03B 5/08

with frequency-determining element comprising lumped inductance and capacitance

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Generation of oscillations using amplifier with regenerative feedback from output to input > with frequency-determining element comprising lumped inductance and capacitance

CPC:

Generation of oscillations using amplifier with regenerative feedback from output to input (H03B9/00, H03B15/00 take precedence) > with frequency-determining element comprising lumped inductance and capacitance

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

3 shared codes have differing titles between IPC and CPC.
