摘要
本文分析了在电力线这一特殊介质中由调制解调实现信息传送的可能性和意义。在这一基础上,基于这一电力线载波通信技术,利用美国国家半导体公司的LM1893电力线调制解调芯片设计出了一个基于这种技术的局域网。
This paper deals with the possibility for modulation and demodulation via power line,the particular transferring medium.Based on these above,a LAN is desig ned by LM1893carrier-current transceiver man-ufactured by National Semiconductor based on power line carrier.
