Abstract
To obtain a timing signal in the regeneration of digital pulses from recordings or after transmission, two start-stop oscillators are triggered, respectively, by signals to be regenerated and by the same signals after inversion. The output signals from these oscillators are combined into a single signal which has the frequency of the desired timing signal, and a flywheel circuit is used to produce a continuously alternating voltage. Each of the start-stop oscillators is conveniently implemented by a pair of transistors whose emitters are interconnected by an inductor and individually connected to an operating voltage via a capacitor and a resistor, respectively.
