A contribution towards the coefficients wordlength determination and its use in computer-aided, microcomputer based compensators design and implementation - The fixed point case

A statistical technique for the coefficient word-length determination in microcomputer based digital com pensators is proposed. This technique uses as design specification the variation on the system output signal when implemented with finite precision arithmetics. Two´s complement fixed-point with rounding arithmetics in used. The computer-aided, microcomputer based compensator design and implementation are also presented.
