一种用单片机测量电容的新方法

A NEW METHOD OF MEASURE CAPACITANCE WITH SINGLE CHIP MICROCOMPUTER

根据一阶线性电路暂态分析理论，提出了一种新的智能化的电容测量方法．该方法采用单片机技术并设计了外部转换电路，无需交流供电及稳频稳压，与常用的电容测量方式相比，具有成本低、测量精度高、范围广和易操作等特点，有开发价值．

A new intellectual faculty method for measure capacitance is introduced.Based on the theory of one step liner circuit temporal form analysis and by single chip microcomputer technique,the extenal transform circuit is designed.It does not need offering power with alternating current and steadying voltage and frequence.Compared with the common measurement method,the new method has low cost,high measuring pricision,wide measurable range and easy operating characteristics.The new method has exploitability.
