摘　　要：现如今随着汽车的普及,广播听众也日益增长,以往靠铁塔的海拔高度、大功率发射机来实现覆盖地区所造成的信号差、盲区等问题,随着调频同步技术的发展,其在广播无线发射中得到大量应用,改善了广播听众的收听体验。本文介绍了义乌市融媒体中心数字调频同步广播项目的设计与建设,对本项目的技术要求、同步音频信号传输、各子站同步发射、发射机远程监控进行讲解。Nowadays,with the popularization of cars,the radio audience is also increasing.In the past,the signal difference and blind area caused by the altitude of the tower and the high-power transmitter were realized.With the development of frequency modulation synchronization technology,it has been widely used in radio transmission,improving the listening experience of the radio audience.This paper introduces the design and construction of the digital FM synchronous broadcasting project of Yiwu Convergence Media Center,and explains the technical requirements,synchronous audio signal transmission,synchronous transmission of sub-stations and remote monitoring of transmitters.
