ABSTRACT:
A vertical deflecting device for use in high defining television receivers which includes an output of a controller connected to a non-volatile memory which is applied through a low pass filter, a digital/analog converter, and an amplifier to one side of a vertical deflecting coil wherein the other side of the vertical deflecting coil is earthed, and a certain programming inputted into a microcomputer which is built therein for easily changing factors such as, for example, frequency, location of vertical deflection, and value of current into a data so that the variation concerning the vertical deflection can be easily changed by changing only data contents.
