Digitizing circuit for anti-ambient light noise |
摘要 |
A system and method of extracting data from a barcode or similar symbol in relatively large ambient light is disclosed. The system uses a slice signal that follows the upper part of a negative offset signal, or the lower part of a positive offset signal, depending upon the value of the input signal. The system may be implemented in digital or analog hardware.
