数字调制系统中改进型增量调制的分析与应用

Analysis of Improvement Type of Increment Modulation in Numerical Modulation System and Its Application

系统地介绍了数字调制系统中改进型增量 (ΔM)调制的原理 ,并与PCM系统中编码进行了比较 ,ΔM编码器使用元件少 ,结构简单 ,很适合在用电系统的二次通讯网中使用。

The artical bescribes the principle of improvement type of increment(M)modulation in numerical modulation system and compairs it with the coder of PCM system.Because of fewer components,M′s coder is simple in structuer and is available to use in second communication net of power supply system.
