ABSTRACT:
A method and device for reading and recognizing an unknown character on a document, the device measuring the character's waveform amplitude along timed intervals and determining that each measurement is within a predetermined acceptable amplitude range at each interval for an ideal character. If all of the measurements of the amplitude are within the acceptable ranges, a recognition signal of the character is generated.
