Title: Impedance measuring device for transient state
Inventor: YUN KAP-KU
IPC: G01R27/28

Granted: 1995-10-16
Abstract: The apparatus comprises a pulse generating part for generating pulse current with a wave, a pulse amplifier for amplifying the pulse, a signal amplifier for amplifying a voltage applied to a ground impedance when the pulse current flows into a compensating impedance and a ground impedance, a sample and hold controlling part for generating a pulse signal after the pulse current is generated from the pulse generating part, and a sampling period and time thereof, a sample and hold part for sampling and holding the signal of the signal amplifier and for changing the signal to an impedance value, an A/D converter for converting an output of the sample and hold part into a digital data, and an LED display for displaying an output of the A/D converter.
