Abstract (in Japanese) (See Japanese page) 
(in English) In order to analyze impedance parameters in biodynamics, the measurement of frequency characteristics with a high time resolution are required.
Therefore we have developed a measurement system for impedance with time resolution of 1 ms.
A voltage $E_A$, which consisted of basic wave and 9 kinds of harmonic wave from 1 kHz to 1 MHz, were converted to current.
The current flowed through human body and a potential voltage, $E_V$ was detected in the measured part.
After A/D conversion of $E_V$ and $E_A$ in the sampling frequency 2 MHz, data number 2048 points, the impedance were calculated. The measured time 1.024 ms was the period of the basic wave and time resolution of this system.
