A multi-wire sensing bridge apparatus is provided to simply and directly correct an electrical signal without using high-order error terms by using first and second impedance units, which are driven by a separated current or voltage source. A multi-wire harness includes plural conductive wires and is electrically connected to the conductive wires. A first impedance unit(208) has a first impedance unit value, a first impedance unit excitation side and a first impedance unit returning side. The first impedance unit excitation side is operably coupled with an electrical signal, which is input to a multi-wire sensing bridge. The first impedance unit returning side is operably coupled with a returning path. A second impedance unit(210) has a second impedance unit value, a second impedance unit excitation side and a second impedance unit returning side. The second impedance unit excitation side is operably coupled with the electrical signal, which is input to the multi-wire sensing bridge. The second impedance unit returning side is operably coupled with the returning path. |
