Vorrichtung zur Gewinnung eines Takt- oder Traegersignales

NOVELTY - The circuit includes a clock oscillator (3) with an adder in a feedback loop for adding the digital data signal to the oscillator signal. The adder has at least one input (6,6') for the digital data signal. The input is connected to a phase detector which also receives the oscillator signal. The phase angle of the oscillator can be adjusted to match that of the data signal. USE - For data detector with demultiplexing function or for carrier recovery from two-phase sampling HF signal. ADVANTAGE - Provides stable operation and simple circuitry. Enables simple provision of clock or carrier signal frequency whose frequency is as high as or an integer multiple of the data signal. DESCRIPTION OF DRAWING(S) - The drawing shows the circuit diagram with a voltage-controlled ring oscillator, a phase detector and a signal preprocessor. ring oscillator 3 phase detector 10 signal preprocessor 15
