In this paper we propose various rotation block realization method of MIMO LBR system. For this, we first discuss how to realize a given LBR system in the form of LBR two-pair cascades. Then we examine several systematic extraction procedures which enable to realize each LBR two-pair in the form of rotation block. Then we consider which realization methods we select for each two-pair block in view of the dynamci range of the coefficients of the rotation blocks. Finally, we demonstrate the LBR realization method using a detailed numerical example that converts a 4th order IIR filter function into a 4*4 transform domain transfer matrix, and then realizes it in a rotation-block cascade.
