| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | DFT(Discrete Fourier Transformation) as we know today is a method of obtaining the frequency component vector from the analog input data vector obtained by time-wise equal sampling sequence.The DFT operation involves a lot of matrix-vector calcutaions of complex exponential functions. In this paper a method of obtaing the frequency componnet vector of the analog input data that is obtained by time-wise unequal sampling sequence.The same matrix-vector calculation procedure is applied, however the values of the matrix componets are much simpler and no calculations of complex exponential fuctions are involved. |
