Abstract
A method and apparatus for decoding a specially encoded bit stream without the use of an external clock. A bit stream is encoded so that the relative lengths of the pulse widths between the transitions in the bit stream are indicative of the type bit being transmitted. A decoder receives the bit stream, measures the lengths of the pulses between the transitions, determines the type of bit by comparing the lengths, and stores the bit in a shift register. The bits can then be output in parallel form.
