Abstract

1,096,038. Transistor oscillator circuits. DYNATEL Ltd. and W. FLETCHER. Oct. 25, 1966 [Feb. 9, 1966], No. 5653/66. Heading H3T. [Also in Division G1] A Wien bridge oscillator comprises transistors 10, 11 forming a non-inverting amplifier with a first feedback path via a capacitor 12 and resistor 13 in parallel, and a second feedback path via capacitor 14 and resistor 15 in series, and includes coils 20, 21 whose inductances are determined by a test pressure acting on a diaphragm near the core 22. Several oscillators operating at different basic frequencies are fed into a common transmitter.
