An unknown waveform representing a scanned character is analyzed by processing a signal through a sequence of different linear filters. The waveform corresponding to the first character is located by finding a well-defined peak. The character is then identified using sequential filters, and a typical waveform length value pre-assigned to the identified character is used to locate the general region in which the next character is likely to be found. A suitable character set is the set of 14 E13B MICR characters described in ANSI Standard X3.2-1970; however, it is applicable to a much less restrictive set.
