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.
