ABSTRACT:
A Digital Automatic Gain Control for a display system having a video display driven by a remote display generator including a display processor which generates binary words that are converted by multiplying digital-to-analog converters to analog deflection voltages that are applied to the video display. The deflection voltages applied to the display are sensed and a digital feedback signal is derived therefrom that is returned to the display generator. The digital feedback signal has a word size larger than the word size of the binary words generated by the display processor. The feedback signal is processed and applied to multiplying digital-to-analog converters and output amplifiers to modify the conversion from binary words to analog deflection voltages to thereby accomplish higher display resolution and accuracy than can be achieved by the display processor alone due to limited binary word size. Higher resolution is achieved because the operation of the converters and amplifiers permits more than one analog output voltage level to be provided for each binary number input to the converters from the display processor.
