| Abstract: | With the rapid development of radio and television technology, the radio and television signal transmission had been all digitized. however, the delay time of digital audio generated in digital transmission path has a great difference. The element of the single frequency network (SFN) of medium-wave(MW) synchronous broadcasting is introduced. Aiming at a variety of transmission way of MW synchronous broadcasting SFN, the various transmission modes of digital audio are explained and each audio signal delay time caused by transport way is specifically analyzed. |
