Used in recovering analog output signal of photocell assembly for reading bars of universal productcode. All four sections of two MC1747 dual opamps are used to amplify and condition photocell output so conditioned output of circuit provides TTL level 1 while wand is scanning black and 0 while scanning white. Additional processing is done by microprocessor such as MC6800.- Microprocessor Applications Manual (Motorola Series in Solid-State Electronics), McGraw-Hill, New York, NY, 1975, p 5.16-5-17.
