随着现代技术的不断进步,尤其是光纤技术的普遍应用,有线电视网络可以完成的功能更趋多样化。但是与传统广播形式的电视网络相比,现在的有线电视网络更加复杂,在制作传播的过程中也更容易受到干扰,加之现在人们生活中的电子设备越来越多,影响有线电视信号质量的因素也越来越多,本文从噪声干扰、电源干扰和交调干扰几方面分析了有线电视网络中的信号干扰问题。
With the continuous improvement of modern technology, especially the widespread application of optical fiber technology, the functions that cable television network can accomplish are more and more diversified. However, compared with the traditional broadcast television network, the current cable TV network is more complicated and more susceptible to interference in the process of production and distribution. In addition, more and more people nowadays have electronic devices that affect the quality of the cable television signal More and more factors, this article from the noise interference, power interference and crosstalk several aspects of the analysis of the signal interference in cable television networks.
