BRIDGE CIRCUIT FOR MEASURING PARAMETRES OF PASSIVE TWO-TERMINAL DEVICES

摘要

FIELD: physics. ^ SUBSTANCE: in each of two series-connected multiple-element two-terminal devices, one of the two branches of a four-arm bridge circuit there is a second capacitors. One of the capacitors had variable capacitance. ^ EFFECT: more accurate measurement of parametres of multiple-element passive two-terminal devices using a bridge circuit with broader functionalities, and reduced error component from the effect of external electromagnetic fields on the measuring device. ^ 1 dwg
