Abstract
A bit of a data signal is encoded with a value of a transmission clock signal if the bit corresponds to a zero. If the bit corresponds to a one, then the bit is encoded with an inverse of the value of the transmission clock signal. After transmission, the encoded signal is decoded by a counter and a comparator. The counter samples the encoded bit of the data signal into a plurality of sampled signals and inverts a portion of the sampled signals. The counter counts the number of sampled signals corresponding to a particular value such as a one or zero. When most of the sampled signals correspond to the particular value, a comparator outputs a decoded signal having a value corresponding to the particular value. When most of the sampled signals do not correspond to the particular value, the comparator outputs a decoded signal having a value corresponding to an inverse of the particular value. The number of sampled signals counted indicates the probability that the decoded signal matches the encoded signal and can be used to determine the integrity of the decoding system.
