Abstract
To assure maximum effectiveness, digital system design parameters must be chosen to optimize human perception. An experimental methodology is described which relates human visual performance and electronic design parameters. These relationships are then used to show how to specify optimal encoder design parameters. To illustrate this experimental procedure, tradeoffs were determined for a digitally encoded television system. These relationships were determined by measuring subjects' minimum perceptible acuities for various length lines and spatial orientations. Visual performance was determined for points along four noise-bandwidth curves representing different information capacities and system costs. Optimum system performance was achieved by maximizing the sampling frequency (bandwidth) of the encoder.
