PROBLEM TO BE SOLVED: To accurately determine data of an arbitrary point other than sample points, in a data interpolation method for determining data of an arbitrary point between adjacent sample points from a sampled data group obtained by sampling J-dimensional periodic analog signal.;SOLUTION: A sampled data group obtained by sampling J-dimensional periodic analog signal is acquired, and data f_p(t₁-t_j) for an arbitrary point in the J-dimensional space is determined.;COPYRIGHT: (C)2009,JPO&INPIT
