| Abstract(in English) | DFT(Discrete Fourier Transformation) as we know today is a method ofobtaining the frequency component vector from the analog input datavector 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. |
