REPETITIVE BYTE RECOGNITION CIRCUIT

Data bytes, encoded into successive groups of n repetitive data bytes, are recovered by selecting a first data byte in each of the successive groups. The first data byte is identified by detecting mismatches in the corresponding bits of successive data bytes. A data byte selector which selects every...

Summary:Data bytes, encoded into successive groups of n repetitive data bytes, are recovered by selecting a first data byte in each of the successive groups. The first data byte is identified by detecting mismatches in the corresponding bits of successive data bytes. A data byte selector which selects every nth byte is aligned in time with the identification of this first data byte and the first data byte of each successive group is selected. In the presence of transmission errors there occurs more than one mismatched data byte within the span of n data bytes. In this event the identified data byte is ignored and the selection of a data byte is accomplished independent of the alignment in time between the data byte selector and the identified data byte.
