This paper deals with the application of lattice wave digital filter (LWDF) (3rd and 5th order) for obtaining an efficient design of a Fractional Delay Filter (FDF). The Real Coded Genetic algorithm (RCGA) and Cuckoo Search Algorithm (CSA) have been used in order to determine the optimal coefficient values of LWDF in order to meet the ideal frequency response characteristics. The simulation of FDF...
In this paper, a new evolutionary optimization technique called flower pollination algorithm is employed to compute the optimal parameters of an unknown infinite impulse response (IIR) system. FPA is inspired by the pollination process of flowers. To achieve a balance between intensification and diversification phases, proper tuning of control parameter has been performed. The proposed FPA based method...
In this paper, an efficient design of a complimentary metal-oxide semiconductor (CMOS) inverter with symmetric switching characteristics is realized using a cuckoo search algorithm (CSA). CSA is an optimization algorithm which is inspired by the brood parasitic behaviour of cuckoos. The performance of the proposed CMOS inverter design using CSA is compared with particle swarm optimization algorithm...
This paper proposes a novel methodology for design and multiplierless implementation of fractional order integrator (FOI) based on lattice wave digital filter using gravitational search algorithm (GSA). The FOI design problem is formulated as an optimization problem using the transfer function of lattice wave digital filter (LWDF). The realization of FOI using LWDF structure increases the accuracy...
This paper aims to design IIR digital differentiator by adopting a new heuristic algorithm called a gravitational search algorithm (GSA). In GSA, agents are treated as the masses and the force of attraction between agents is calculated based on Newton's gravitation law to find optimal solutions to the problem. The agent with greater mass is treated as the near optimal solution and their position is...
In this paper a new heuristic algorithm called Gravitational Search Algorithm (GSA), is employed for the optimization of the filter coefficients of infinite impulse response (IIR) integrator design problem. GSA is a population based algorithm formulated on the principles of Newtonian gravity and law of motion. GSA employs the interaction of masses in an isolated system directed by law of Newtonian...
