Abstract
An intelligent gain selection circuit replaces the gain set by an automatic gain control circuit in an electro-optical reader for reading indicia, such as bar code symbols, with a larger gain where specular reflections, high contrast edges, or other noise operative to produce dominant high voltage peaks in an analog signal generated by a sensor in the reader, are detected.
