Abstract
A process and apparatus for synchronizing the block counter of an RDS radio data receiver is described. According to the process, the bits stored in a 26-bit shift register, are cycled at least n times in said register, n being the number of allowable offset words, and the shift register content is X-OR gated with another offset word in a given sequence for each cycle. The gating result is received by a syndrome detection circuit, which triggers a sync pulse when the zero syndrome is detected, and the sync pulse resets the bit counter to zero and sets the block counter to the address counter status assigned to the offset word in the offset word generator.
