| 摘 要： | 为了节省对发射台的投资、节省占地面积,目前中国有很多中波广播台都采用多频共塔的工作模式,但是多频共塔在节约经济成本的同时,其自身带来的干扰问题严重影响了广播的质量。先介绍了噪声、干扰的概念以及多频共塔中干扰的产生问题,然后结合本台实际,提出了正确设计匹配网络与阻塞网络、合理设计及选择陷波网络、经常维护系统、采用优质音频传输线、加强屏蔽等可以有效消除干扰的措施。

| Abstract: | To cut the investment of transmitting tower and save the areas,many MW tower in China operates at the mode of multi-frequency total tower.However,the multi-frequency total tower mode has the shortcoming of large interference.Thus the concepts of noise and interference,and the production of multi-frequency total tower are studied.Then in combination with the actual situation,effective measures to eliminate interference are proposed,including correct design of matching network and blocking network,rational design and selection of notch network,regular maintenance of the system,and so on. |

| Keywords: | multi-frequency total tower interference blocking network notch |
