H03B 5/38

frequency-determining element being connected via bridge circuit to closed ring around which signal is transmitted

Introduced: September 1968

Title

Titles differ between systems:

IPC: the frequency-determining element being connected a bridge circuit to a closed loop in which the signal is transmitted

CPC: frequency-determining element being connected via bridge circuit to closed ring around which signal is transmitted

Full Title

Full titles differ between systems:

IPC:

Generation of oscillations using amplifier with regenerative feedback from output to input > with frequency-determining element being electromechanical resonator > being a piezoelectric resonator > the frequency-determining element being connected a bridge circuit to a closed loop in which the signal is transmitted

CPC:

Generation of oscillations using amplifier with regenerative feedback from output to input (H03B9/00, H03B15/00 take precedence) > with frequency-determining element being electromechanical resonator > being a piezoelectric resonator (selection of piezoelectric material H10N30/00) > frequency-determining element being connected via bridge circuit to closed ring around which signal is transmitted
