Abstract: This paper proposes an efficient optimization technique, called Predator Prey Optimization (PPO) for designing an optimal Band Stop FIR digital filter. PPO is a stochastic population based optimization technique that provides optimal filter coefficients and solves local stagnation problem of Particle Swarm Optimization (PSO) technique as the predator produces diversification and results into optimum solutions. PPO is capable of performing local as well as global search. The obtained simulation results show that PPO is superior to PSO. PPO provides robust FIR digital filter and optimizes the filter design by minimizing the value of design parameters that are magnitude errors, pass band ripples and stop band ripples.
