natural binary

Encoding system of absolute encoder generally uses natural binary code,Gray code,Gray-excess-code and so on.

绝对式编码器编码码制通常采用自然二进制码、格雷码、格雷余码等。

It also compares the advantages and disadvantages of natural binary code and Gray code.

为了克服跨时钟域逻辑设计中的异步问题,文章提出并实现了—种基于Gray码的时钟域切换技术,并充分比较了异步FIFO读写指针利用自然二进制码与Gray码进行设计的利弊。
