@@@@In allusion to the complex structure of the current measuring instrument for inductance capacitance which is lack of accuracy, this paper proposes a measurement method of the high precison inductance and capacitance parameter tosolve the problem. The measurement of inductance and capacitance is translated into DC voltage measurement with the measuring method based on digital waveform storage technique and analog-digital hardware multiplication operater. Through theoretical derivation, academic expressions of inductance and capacitance are developed. The error of method and the factors influencing measurement accuracy are analyzed. The Matlab simulation results indicate that the relative error calculated by this algorithm is constant. The algorithm offers a reliable scientific method for the measurement of inductance and capacitance.
