Abstract
A method and device for finding a reference pattern in a serial stream of digital data draws up comparison tables for the front and rear bits of the reference pattern. Using the comparison table for the front bits, bits which in terms of time are located upstream of a point P in the data stream are compared, and using the comparison table for the rear bits, bits which in terms of time are located downstream of point P in the data stream are compared. Next, the number of bits matching the reference pattern upstream and downstream of the point P are added up, and in case the sum total is greater than or equal to the number of bits in the reference pattern, there is a signal that the reference pattern has been found.
