It is not difficult to show that his definition can be expressed in the form of Eq. . Wiener obtained the formula by use of a real unitary transformation. However, in general, the unitary transformation which diagonalizes the coherency matrix is a complex matrix. To perform the diagonalization physically one has, in general, to make use not only of a rotator (real transformer) but also of a phase plate (complex transformer). [CrossRef]
