FREQUENCY AND TIME COLLECTIVE STANDARD Russian patent published in 1994 - IPC

FIELD: radio engineering. SUBSTANCE: standard has n identical channels which operate simultaneously. Any channel has frequency and time standard 1, frequency difference multiplier 2, frequency difference detector 3, controllable voltage amplifier 4, trouble turning off device 5. Frequency autotuning of output frequency of generator 8 which is controlled by voltage is carried out according to sum of normalized output voltages of voltage adder 7. For accounting changes in average frequency the correction for the frequency is introduced into phase corrector 9. Time scale former 10 forms pulses of time precise scale of collective standard which is compared from time to time with scales of individual frequency and time standards 1. These comparison is performed by measuring, computational and control system 6. EFFECT: improved long-time stability. 7 dwg
