摘要: A circuit realization is presented for four-dimensional (4D) lattice-ladder discrete filters. The proposed 4D requires, its implementation, a minimum number of delay elements. Further, the dimension state-vector, derived state-space model, minimal and transfer function characterized by all-pass property. step-by-step low-order example provided to demonstrate minimality both, circuit, realizations. An educational conjointment lattice filters with lower (2D, 1D), imparted.
