A comprehensive analysis of realization of digital filters with complex coefficients obtained by decomposition of real digital filters, using complex and real allpass networks, is given in the paper. Realization of complex coefficient filters obtained directly in the z domain is also discussed in the paper. An analysis of hardware costs for different structures used for realization of complex coefficient filters is presented.
