摘要
为克服机械电位器调零的局限性,从介绍数字电位器的原理出发,详细地给出了采用数字电位器来实现自动调零的具体电路,并从原理上分析了电路的工作过程,说明该电路能完成自动调零工作。
In order to overcome some shortages of mechanical potentiometer,the principle of Digital Potentiometer is first introduced.And the material circuits which are used to realize zero adjust automatically are detailed.The processes of realization of these circuits are analyzed detailedly in principle.It shows these circuits can realize zero adjust automatically.
