<P>PROBLEM TO BE SOLVED: To provide an autocorrelation detector capable of automatizing delay adjustment between a data signal and a clock signal. <P>SOLUTION: The autocorrelation detector includes a correlation portion 20, a gate 30, a clock delay portion 40, a gate delay portion 50, and a data identification determiner 60. The data identification determining section has a memory 64, a clock delay changing means 72, a gate delay change means 74 and a strength comparison means 76. The clock delay changing means changes the amount of clock delay given to a clock pulse. The gate delay change means changes the amount of gate delay given to a gate pulse; the strength comparison means compares an output strength of the gate with a stored strength stored at the memory 64; and when the output strength is larger than the stored strength, the output strength, the amount of clock delay, and the amount of gate delay are stored in the memory as a stored strength, a stored amount of clock delay, and a stored amount of gate delay, respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT |
