摘　　要：从目前的工程观点来看,一个本身不稳定的A/D 变换器是不可能用来进行精确的A/D 变换的。本文提出可用极不稳定的混沌电路实现精确稳定的A/ D 变换,并且可随意改变为2 、3 等进制的A/D 变换。虽然其精度目前还未超过现有的A/ D 变换器,但这是一种全新意义上的A/ D 变换。In present engineering point of view, accurate conversion of A/D converter can't realize which is made of unstable system. But in this paper,it is proposed that it can be accurately A/D convert with extremely unstable chaotic circuit. And adjusting the parameters, it can be a binary, trinary or N nary A/D converter arbitrarily.Although the precision of it have not exceeded present A/D converter, it is based on a concept completely opposed to the traditional engineering viewpoints. It is worth while studying the problem in a common effort.
