DEVICE WHICH MEASURES SHIFT BETWEEN DISTRIBUTED TIME BASES Russian patent published in 1996 - IPC

FIELD: devices for unified time. SUBSTANCE: device has local clock 1, reverse counter 2, four-input clock frequency divider 3, clock oscillator 4, transmitter start pulse generator 5, transmitter 6, receiver 7, signal separator 8, recorder 9 and counting control signal generator 10. EFFECT: single-valued measurement of shift for arbitrary absolute values and signs of shift, measurement does not depend on time for signal propagation between points with reference and local clocks and on time for signal delay by generator of transmitter start pulses. 10 dwg
