Introduction 33 It is possible to reverse the transformation to obtain g( i)T values from a sampled frequency spectrum, G,. This process is achieved by applying the inverse discrete Fourier transform (IDFT), which is defined as 1 N-1 g(i)T = - - ~ N r=O i =0,1 ,2, ... 18 using the DFT method. Comment on the result.
