电视信号中的标准频率在同步广播中的应用

The Application of the Standard Frequency in Television Signals to the Synchro-broadcast

电视信号中的标准频率信号是受原子钟控制的高稳定度、高准确度的信号。无疑,此信号的应用也是一种资源利用。根据中波同步广播的需求,介绍几种利用电视信号中标准频率的方法。用这几种方法,同样可以满足其他部门对频率标准的需求。

The standard frequency in television signals is a signal with high stability and accuracy, controlled by the atomic clock. Undoubtedly application of this signal is a exploitation of source. In this paper some mathods of using the standard frequency in television signals are introduced according to the requirements in the medium frequency synchrobroadcast, and these methods can also be used in other cases.
