微机控制系统设计是多变的,必然要遇到反映模拟信息极性的二进制数字信号的编码、它们之间的相互转换,以及如何实现极性控制问题。文章论述了单极性的二进制编码、双极性的编码,然后讨论极性转换与控制的实现,并例举了 AD/DA 转换。本文所讨论的极性问题和实现方法,对于实时过程系统设计有一定的参考和应用价值。
Microcomputer control system design is changing, it is bound to encounter the reflection of the polarity of analog information binary digital signal coding, conversion between them, and how to achieve polarity control. The article discusses unipolar binary coding, bipolar coding, and then discusses the implementation of polarity conversion and control, and illustrates the AD / DA conversion. The polarity problem and the implementation method discussed in this paper have some reference and application value to the design of real-time process system.
