ABSTRACT:
The deflection system includes a first pair of deflection coils connected in series for moving the beam of a cathode ray tube in a horizontal direction and a second pair of deflection coils having a choke connected in series therebetween with a first capacitor connected in parallel with the choke and one coil and a second capacitor connected in parallel with the choke and the other coil to linearly add a relatively low and a relatively high frequency deflection signal for moving the beam in steps vertically across the cathode ray tube and linearly in small vertical sawtooths between the steps.
