Abstract

The proposed quasibalanced bridge for separately measuring the parameters of nonresonance four-element two-terminal networks contains a reference reactive element connected in the arm of the bridge with a controlled element in one of the other arms, a differentiator unit, an integrator unit, a digital voltage divider, an additional balance state detector, an additional reversible pulse counter, and a frequency divider. The bridge can be in two states of quasibalance. Each of these states is determined by the detector as the state in which the real component of the ratio of the complex voltages at the bridge outputs does not depend on frequency.
