Optimal Design of Riesz Fractional Order Digital Differentiator using Arithmetic Optimization Algorithm for QRS Complex Detection

An optimized zero phase response fractional order digital differentiator called Riesz Fractional order digital differentiator is proposed in this article by applying recently developed metaheuristic algorithm called Arithmetic Optimization Algorithm for accurate ECG QRS detection.The zero phase response helps to preserve the features of differentiated ECG and magnitude characteristics of proposed AOA based Riesz Fractional Order Digital Differentiator helps to obtain highly differentiated ECG.These two primitive properties of proposed Riesz Fractional order digital differentiator accomodate QRS detector to identify R peaks location more precisely.The suggested Method is evaluated using MIT-BIH Data Base. The matlab tool is used to evaluate the experiment results.
