Improved Design of Digital IIR Second-Order Differentiator Using Genetic Algorithm

Abstract

In this paper, a new design of digital differentiator of the second order using genetic algorithm is presented. By the use of genetic algorithm, transfer function differentiator of second order is derived. Then compare the results with the ideal second-order differentiator. Result is also compared with digital IIR differentiator second order using backward difference formula which is already exist.
