Synthesis of Complex Discrete Filters
Abstract
Synthesis methodology of the non-recursive and recursive complex discrete filters is examined on the base of the methods of the invariant impulse and transition characteristics, and on the base of z-transformation method. It is shown that complex filters contain two quadrature channels allowing easily to change the filter tuning frequency. This makes them very effective when adaptive and coherent systems for information processing are created. Specific examples of complex discrete filter arrangement are provided.
