<p>A cathode ray tube includes a deflection unit. A coil system of the deflection unit is provided with a conductive layer, the value for fmax/Δf ranging between 0.5 and 10, Δf being the half-value width of the impedance curve around a peak frequency fmax, and fmax being greater than 1 MHz. This results in a reduction of ringing phenomena.</p> |
