    摘要： A deflection system for a cathode-ray tube (16) including a horizontal deflection coil (2), a magnetic core (4), and a vertical deflection coil (3) toroidally wound on the magnetic core (4). The vertical deflection coil (3) has a plurality of superimposed winding layers arranged with respect to a vertical axis of the deflection system with at least one of the layers of the vertical deflection coil (3) being disposed asymmetrically with respect to the vertical axis or disposed symmetrically with respect to the vertical axis and having winding portions delimiting at least one gap along an extent thereof at a position other than the vertical axis (6). In this manner, an induced voltage in the at least one of the layers is substantially equal to an induced voltage in each of another of the layers at least in the region of the vertical axis (6), whereby ringing is substantially prevented.
