ABSTRACT:
An arrangement for acquiring signal representatives intended to correspond to character representations, out of a set of possible character representations, provided on a substrate that emanate magnetic fields which can be sensed to provide a related waveform. Times of extrema of the waveform are ordered and compared with the ordering of time locations in waveforms expected for the set of possible characters with different orderings being used to eliminate those possible characters having expected waveforms incompatible with the extrema ordered times of the measured waveform.
