PURPOSE:To attain visually smoothing, through equalized intervals of beam positions on a display screen, by providing a modulation voltage to displace the entire electron beam position from a plurality of line cathodes on a screen, for a deflection signal. CONSTITUTION:Vertical and horizontal synchronizing signals separated from a television composite video signal are applied to binary-hexadecimal decoder 81 via a signal processing circuit (not shown) to produce an output of 16-level of step waves. This step wave is applied to an output stage amplifier 84 with suitable shaping depending on a voltage preset at a volume control 82, and a DC level of the amplifier 84 is changed with a correction circuit 86 consisting of a volume control 88 and an analog switch group 87 to shift a DC level corresponding to each line cathode, allowing to substantially equalize the interval of position of beam. |
