Abstract
A balanced-to-unbalanced transformer for interconnecting a balanced signal transmitted on a balanced cable and an unbalanced signal transmitted on an unbalanced cable through a transformer. Common-mode impedance is reduced by grounding a center point of two or more impedance elements between signal lines on the balanced cable side of the transformer to a signal circuit ground or a frame ground on the unbalanced cable side of the transformer.
