Deflection circuit for cathode ray tube with geometry correction independent of the deflection frequency

摘要

The voltage sweep circuit has two oscillating circuits in parallel between a switch (T) each having a capacitor (Cr,Crm) a diode (D,Dm) an inductance (Ld,Lm) and a voltage source (Cs,Cm). The second oscillating circuit has an amplifier (12) and feedback mechanism adjusting the voltage level to a preset value.
