Title:
共通周波数ネットワークの高周波送信機を同期させる配列物
Document Type and Number:
Japanese Patent JP4709924
Kind Code:
B2
Abstract:
The arrangement has high frequency transmitters (S1-SX) provided with digital data stream (TS) in the form of periodic data frame. A reference transmission time is computed in the transmitters from a synchronization time-stamp. The reference time is compared with an actual transmission time for each transmitter, where the actual transmission time is determined by a system clock, and clock frequency of a clock generator is controlled by a control circuit such that the actual time determined by the system clock corresponds with the reference time.
