In general, a(n/N) and b(nlN) are as given in Eqs. (29) and (30), respectively.
Direct current a(0) is as given in Eq. (31).
The inverse Fourier transform is given in Eq. (32).
The Fourier transform is expressed using complex numbers as follows:
The inverse Fourier equation is as follows:
Here a rotator <|> is introduced, as expressed in Eq. (35).
The following equations are introduced by using Eqs. (35) and (36).
