FIELD: synchronous transmission of data. SUBSTANCE: to obtain clock phase criteria in the communication system receiver, two adjacent values of count for duration of symbol 2 are formed from received signal, as well as an additional intermediate value of count lying in the middle between these two values. For such a clock phase detector jitter, depending on the repeating structure of digital signal, should be eliminated. It is attained by modification of the Gardner method, which takes into account the influence of noise of adjacent symbols on the clock phase criterion. EFFECT: reduced natural jitter. 2 cl, 8 dwg
