Abstract
A circuit within a video monitor for making corrections during horizontal scan includes a data storage device containing information relating to a selected display parameter, an integrator receptive of the stored information and adapted to produce an integrated signal therefrom, and an amplifier receptive of the integrated signal for supplying signals to the video monitor based on the integrated signal. The information supplied from the data storage device to the integrator is encoded in a pulse density modulated wave form via a tri-state gate and a one-shot timer. The information stored in the data storage device is stored in bytes, each byte containing a "sign bit" and a plurality of data bits.
