Effect of Hard Limiting on the Recognition of Gram Type Displays

Abstract

Intensity modulated gram displays are often stored digitally for later display generation, or are displayed on devices of limited dynamic range. The display degradation when using a limited number of gray tones is thus of interest. An experiment was conducted to determine the degradation for hard- limited displays where only one-bit quantization is used. An effective increase (degradation) in recognition differential of about one decibel was measured for this system relative to a linear system, for both visual and electronic integration performance, for both linear and hard-limited data.
