Abstract
A data demodulating technique for binary data defined by a pulse code modulated signal. The technique involves digitizing the data signal read by a magnetic head from the stripe of a magnetic card. The time interval between peaks in the digitized signal is determined to provide peak interval values. The peak interval values form the basis for determining the end of a character and also by a pattern matching technique against idealized data form the basis for determining the character itself.
