Abstract
A symbol decoding system incorporated in a NMOS/LSI chip generates asynchronously binary data in response to the scanning of bars and spaces of the symbol. The binary data may represent each bar or space as a numerical character, a margin or a center band of the symbol. The binary data also includes data identifying the bar or space and if the character generated is valid or invalid. Logic circuits generate a time delay period allowing the binary data to be generated asynchronously during the delay period. At the end of the delay period the binary data is outputted to a utilizing device for selecting the valid data from the data outputted by the decoding system.
