Abstract
QUARTERS Ⅱ designed a 8-bit Barker code signal generator, the generator has a single and continuous output. Barker Code is mainly used in communication systems frame synchronization, which is characterized with a sharp auto-correlation function for the digital information and the random Differentiated, easily identifiable, there's the possibility of pseudo-synchronous small. Barker Code is a law of a special group of binary code, it is a non-periodic sequence.
Key words: QUARTERS Ⅱ， Barker code， signal generator，sequence
