  • Field deflection circuit for use in a picture display device
    Patent number: 4755727
    Abstract: A field deflection circuit for use in a picture display device, comprising an amplifier to whose output the series network of a field deflection coil, a separated capacitor and a negative feedback resistor is disclosed. A circuit is provided in parallel with the separating capacitor for fixing the d.c. component of the voltage across the capacitor at a more less constant value. Frequency-dependent negative feedback networks may therefore be omitted.
