DIGITAL DATA RECEIVING DEVICE Russian patent published in 2003 - IPC

FIELD: communication engineering; digital data transmission system. SUBSTANCE: device designed to automatically determine error signal of speed at sending and receiving ends and to bring them to desired consistency by generating standard frequency for obtaining clock frequency at receiving end corresponding to speed of arriving information has master oscillator, standard-frequency generator, signal analyzer, clock frequency generator, decoder, and speed code shaper. Rise and fall times used as time stamps in shaping clock frequency at receiving end and as speed error signs at sending and receiving ends are separated from signals arriving at device data input which are resented by double-space frequency-modulated, and phase-keyed channel codes. After that pulses are generated for varying standard frequency rating to eventually generate clock frequency at receiving end corresponding to speed of signals arriving at data input of device. EFFECT: facilitated determination of speed error sign at sending and receiving ends. 1 cl, 4 dwg
