<p>PROBLEM TO BE SOLVED: To provide a data signal variable delay system for reducing a signal distortion.SOLUTION: A data signal variable delay system 100 includes a delay unit 110 and a phase interpolation unit 120. The delay unit includes a plurality of delay elements 112a, 112b, and 112n each having an element delay, and is formed so as to generate a plurality of delay signals 118 by delaying a data signal 102 using the plurality of delay elements so that each of the delay signals has a different delay. The phase interpolation unit is connected to the delay unit and includes a mixer 122, the mixer mixing two delay signals on the basis of a mixing weighting selected for the two delay signals and generating a final delay data signal 128 which is a data signal delayed by a final delay. The mixing weighting may be selected on the basis of the final delay.</p> |
