Abstract

1,078,464. Pulse generators. VAKUTRONIK VEB. Oct. 12, 1964, No. 41566/64. Heading H3T. A push-pull square-wave generator comprises transistors 4, 5 with feedback through a resistor 16 from a transformer 7 the primary of which resonates with a capacitor 6 to determine the operating frequency, the amount of feedback being sufficient to ensure squarewave operation. An RC circuit 8, 10 across the secondary of the transformer provides an output of adjustable phase, which is taken off through an amplifying transistor 12. Outputs are available at terminals 13 and 14 with a controllable phase difference. Resistor 3 provides temperature stabilization of the operating point of the oscillating transistors. The output can be used for controlling the demodulator in dynamic-capacitor amplifiers, and is independent of load fluctuations.
