INTERPOLATION IN THE DIGITAL UNBALANCED IMPEDANCE COMPARATOR

Kamil Kontorski

Abstract

Some details about digital balanced and unbalanced impedance comparators are presented in this article. A method of measuring an impedance ratio using the digital unbalanced comparator is described. Considerations about measurement errors connected with an experimental comparator setup are included. The research results are in an agreement with the theoretical assumptions.
