Designing of a Tunable Fractional Order Chebyshev High Pass Filter Using Particle Swarm Optimization

Fractional order Chebyshev high pass filters have been designed in this paper for orders (1+α), (2+α) and (3+α), α representing the fractional component. The work has done by using nature-inspired evolutionary metaheuristic technique called particle swarm optimization. MATLAB simulations these shown with varying from 0.1 to 0.9 at a step of 0.1. attenuation values are compared ideal values. canonical forms (1+α) realized OTA based KHN filter.
