Abstract
A wave form representative of the character to be recognized is converted digitally. For each set of N sample reference signals initially acquired, the absolute value of the difference between the numerical value of each sample reference signal and the numerical value of each sample signal to be recognized is calculated in order to establish K lists each of N absolute values. From the K lists is selected that for which the N absolute values have an approximately constant value, where the character to be recognized corresponds to the reference character associated with the list thus selected.
