ABSTRACT:
A continuously rectifiable linearity coil circuit having a saturated transformer serially connected with a deflection yoke of a computer monitor, a linearity coil and a control circuit. In a nearly saturated state, the inductance of the saturated transformer decreases when the input DC current increases. Accordingly, by changing the value of the current passing through the linearity coil, the wave form of the deflection current passing through the deflection yoke is changed so as to keep the horizontal linearity of the computer monitor optimal with respect to different input horizontal frequency signals.
