Realization of complex digital filters based on the LBC two‐pair extraction procedure
José I. Acha, Francisco Torres · International Journal of Circuit Theory and Applications · 1990
Abstract The synthesis of real digital filters based on the lossless bounded real (LBR) two‐pair extraction procedure is extended to the complex domain. the only component then required is a first‐order reciprocal lossless bounded complex (LBC) two‐pair. This two‐pair permits the synthesis of any bounded complex (BC) or lossless bounded complex (LBC) digital transfer function. Lastly, a unitary implementation in terms of Givens (planar) rotation modules is given for the proposed two‐pair.
