Abstract
A digital display unit including an analog to digital converter (ADC). When the optimal sampling frequency for sampling an analog display signal is greater than the maximum sampling frequency of the ADC, the analog display signal is sampled using 2:1' interleaved sampling. A smaller image represented by the sampled values is then upscaled prior to being displayed. Such upscaling compensates for the decreased number of samples that would be generated by sampling at lower sampling frequency during 2:1 interleaved sampling.
