进行调频广播覆盖网规划是一项庞大的、复杂的系统工程,规划中指配频率极为重要.而调频与调频、调频与电视频率组合(同台、同覆盖区或收转、差转)时相互制约因素较多,为避免相互干扰,必须弄清这些制约关系.“调频与调频、调频与电视频率组合时各种干扰情况表”介绍的是除同、邻频干扰以外的其它几种主要干扰,供指配频率时参考.表中各项内容介绍如下:第1项:频率f_1(MHz).按我国无线电频率划分规定,调频广播使用87～108MHz.为避免对其它业务的
FM radio coverage network planning is a huge, complex systems engineering, planning the frequency of assignment is extremely important.While the FM and FM, FM and TV frequency combinations (on the same, with the coverage area or close, poor turn) each other There are many constraints, in order to avoid mutual interference, we must clarify these constraints. “FM and FM, FM and TV frequency combinations of various interference table” describes in addition to the same, adjacent to the interference of several other major interference , For reference when the frequency of allocation Table in the table below are described: Item 1: Frequency f_1 (MHz). According to China’s radio frequency division requirements, FM radio use 87 ~ 108MHz. In order to avoid other services
