DEVICE FOR SYNCHRONIZATION OF CLOCK AND CARRIER FREQUENCIES Russian patent published in 1997 - IPC

FIELD: transmission channels for digital time-base and frequency-base converters. SUBSTANCE: device has controlled frequency divider 1, frequency divider 2, control gate 3, unit 4 which detects error in frequency-base signal for synchronization of clock frequency, memory units 5, 12, 13, Fourier transform unit 6, adder 7, subtraction unit 8, gate 9, control value generator 10, timer 11, switch 14, on-line memory unit 15, master oscillator 16, carrier frequency synchronization unit 17, unit 18 which detects error in carrier-frequency synchronization signal, carrier frequency oscillator 19, synchronous detector 20, control unit 21. EFFECT: increased speed of synchronization detection for clock and carrier frequencies. 1 dwg
