Supremacy of trigonometric mutation strategy for efficient design of multiplier-less low-pass FIR filter using differential evolution algorithm

In this communication, we have investigated the effect of trigonometric mutation strategy of Differential Evolution (DE) algorithm for the design of hardware efficient multiplier-less Finite duration Impulse Response (FIR) filter. The resulting filter performance has been compared and properly analyzed with the one designed by rand/1 mutation technique of DE and other existing multiplier-less structures from various angles. Finally, the design efficiency of our proposed filter over the other models has been firmly established by listing a number of performance parameters.
