PROBLEM TO BE SOLVED: To provide an auto-correlation device capable of reducing power consumption by reducing the number of arithmetic processing. SOLUTION: In this auto-correlation device, an A/D converter 1 converts an analog signal into a digital signal, and a digital sampling part 2 samples digital signal and an analog sampling part 3 samples analog signal respectively. Further, the analog sampling part 3 delays the sample values according to a shift clock signal outputted from a clock generation part 6, and an integration part 4 and adder part 5 calculate a scalar product of both sampled values, to output it as an auto-correlation value. |
