Abstract
A method and apparatus for recognizing MICR characters having positive peak values, negative peak values, and substantially zero values occurring at predetermined clock positions along the associated waveform. A first count derived from the speed of the MICR characters moving past the associated reader is used for deriving nominal clock pulses for clocking the peak and zero values into storage registers associated with the apparatus. The occurrences of positive and negative peak values are used to adjust the first count depending upon whether the MICR characters are moving faster or slower than a nominal rate, with the adjustment being used to provide an adjusted count which is used for determining subsequent clock pulses.
