前言调频广播使用88～108MHz,其中88～92MHz与电视五频道重叠,彼此很容易产生干扰。为了避免相互干扰,在指配有关频道时需要确定应予采取的射频保护率。在安徽省广播局协助下做了这方面的试验。现根据试验结果,提出一些分析。
Preface FM radio use 88 ~ 108MHz, of which 88 ~ 92MHz and TV five channels overlap, it is easy to interfere with each other. In order to avoid mutual interference, it is necessary to determine the RF protection rate that should be taken when allocating the relevant channel. With the help of Anhui Broadcasting Bureau to do this experiment. Now based on the test results, some analysis.
