ABSTRACT:
A symmetrically wound signal transformer having a first primary coil portion wound in one groove on a bobbin and a first secondary coil portion wound in an adjacent groove on the bobbin. A second primary coil portion, of shorter length than the first primary coil portion is wound in a reverse direction in the groove containing the first secondary coil portion. Likewise, a shorter second secondary coil portion is wound in a reverse direction in the groove containing the first primary coil portion. The respective second coil portions serve as decoupling windings.
