Abstract
A linear direct current amplifier with automatic gain control system for regulating the peak-to-peak amplitude of the signal output that is acquired by scanning a coded label with a hand-held photo optical scanner is disclosed. The gain is set primarily by the white background on the coded label and it is further adjusted at the black bar as the pen passes over the label surface on which the code is imprinted. Control circuit feedback compensates for input amplitude and contrast variations.
