Two Parameter (2D) Measurements in Four Terminal (4T) Impedance Bridges as the New Tool for Signal Conditioning (1). Part 2 Measurements of Two Variables (2D)

Zygmunt L. Warsza

Abstract

Two-part paper presents the synthesis of some author’s works on unified backgrounds of immitance multivariable (nD) measurements of few jointed variables and on the unconventional signal conditioning in four terminal (4T) bridge circuits used for that. In the Part 1 four different circuits for 2D measurements was proposed. Short description of equations and main parameters of the 4R bridge as X type twoport with variable parameters and then as circuit 4T unconventionally supplied by two current sources, named double current bridge (2J) are given and shortly discussed. In the Part 2 application of both types of 4R bridges for 2D measurements is presented and discussed in details
