An interesting problem of filtering theory is discussed: given some types of symmetries of a signal (or of its Fourier transform (FT)) what are the symmetries induced for its FT (or for its corresponding signal). The symmetry is expressed by a set of parameters entering the signal of its FT. Multidimensional FT are considered. Applications for continuous time and for discrete time signals are given. The results may prove to be very useful in the design of 2-dimensional digital filters.
