Abstract
A decoder decodes a predetermined binary pattern from within a data stream, wherein the pattern includes a repetitious series of binary digits and each series of digits is composed of 2N bits, N being a positive integer greater than 1, and the first N bits is the complement of the second N bits of the series. The decoder includes a bit synchronizer for synchronizing to the bits of the pattern, a digital phase locked loop for generating a clock signal from the received data, a comparator and memory for analyzing the data stream in an alternating manner so as to generate N paths, wherein each path receives every Nth respective bit of the data stream, and an arithmetic logic unit for calculating and measuring the integrity of the pattern in the received data.
