ABSTRACT:
A magnetic stripe decoder includes an amplitude discrimination circuit to remove noise due to glitches. The use of amplitude discrimination rather than a filter, which is in common use today, permits a single decoder circuit to decode data over a wide range of frequencies including the standards 75 BPI and 210 BPI. In the absence of such an amplitude discriminator, two different decoders, one for 75 BPI and one for 210 BPI are necessary.
