无线电广播电台对通信电缆线路的影响表现为对电话通路的干扰,对传输系统线路频谱的干扰频率就是无线电台的载波频率。此外,还表现为正向及倒置频谱的噪音。许多由气候(或季节)条件决定的作用参数引起幅度—相位变化而导致干扰。在双线回路中沿线路存在着分布不平衡的随机性,致使各单个电缆回路中由于作用参数变化的相关性微弱,而引起干扰变化。这就减低了文献中研究的以补偿方法为基础构成设备的干扰抑制效率。
The effect of a radio station on a communications cable line is manifested by interference with the telephone line, and the interference frequency with the transmission system line spectrum is the radio station carrier frequency. In addition, the performance of the forward and inverted spectrum noise. Many climate-dependent (or seasonally) acting parameters cause interference due to amplitude-phase changes. In the two-wire loop along the line there is the uneven distribution of randomness, resulting in a single cable loop because of the weak correlation between the changes in parameters, which caused interference changes. This reduces the interference suppression efficiency of the devices based on the compensation method studied in the literature.
