【Abstract】 An electrochemical transient measurement system has been established by exchanging information between a native electrochemical measurement unit and a personal computer through a PCL 812 interface card. Interface software for windows was developed so that a rapid and precise way of data acquisition could be obtained. Several methods of software digital filter have been provided to diminish the impact of noise. The measuremental results of an equivalent circuit showed that this measurement system is reliable.更多还原
