HORIZONTAL RASTER POSITIONING |
摘要 |
A raster position adjusting circuit for controlling the raster position on a CRT, the circuit being equipped with a constant-current supply source and a voltage-controlled type current supply source which are coupled to each other. The drawing current of the voltage-controlled type current supply source is arranged to be controllable in accordance with the output voltage from a digital-to-analog converter, thereby controlling the emitter-base voltages of first and second transistors connected to a junction point between both the current supply sources. This control of the emitter-base voltages of the first and second transistors allows the control of the direction and value of a current flowing through a horizontal deflecting coil, thereby effecting the raster position adjustment. <IMAGE> |
