THE INFLUENCE OF SAMPLING PARAMETERS ON ACCURACY OF CAPACITANCE MEASUREMENT IN THE METHOD BASED ON DSP

Grzegorz Lentka, Jerzy Hoja

Abstract

The paper presents the method of measurement of impedance parameters based on measurement signals sampling and DSP. The influence of main sources of uncertainty and errors on capacitance measurement accuracy has been analysed. The following have been included: non-synchronous sampling of two measurement signals proportional to current and voltage on impedance under measurement, A/D converter resolution and total number of collected samples. The results of simulations have been presented.
