Full Band IIR Digital Differentiators Design Using Evolutionary Algorithm

This article proposes an IIR full-band digital differentiator (FBDD) design methodology by using a competitive metaheuristic optimisation technique called crow search algorithm (CSA). The CSA based FBDD design attains the most accurate characteristics to the ideal FBDD as compared to the standard optimisation methods such as differential evolution (DE) and real-coded genetic algorithm (RGA). Moreover, the CSA based FBDD design results sensibly surpass state-of-the-art reported FBDD design approaches.
