This paper presents a novel generalized structure of adaptive filter by using state equation description. Although many structures have been used widely, including transversal and lattice structure, it is necessary to propose a generalized structure for realizing a high performance adaptive filter with low residual error and high convergence speed. The generalized structure proposed in this paper is consisted of signal feeder, linear combiner and processor. This structure, called as "combined type adaptive filter, " is able to contain any FIR system and IIR system with fixed poles. In terms of the output control-lability matrix, some characteristics of this structure have been described. A theorem on the minimum mean-equare error is also developed. Furthermore, to demonstrate the availability of this structure, computer simulation results are given.
