Differential Evolution Biogeography Based Optimization for Linear Phase Fir Low Pass Filter Design

Surekha Rani, Balwinder Singh Dhaliwal, Sandeep Singh Gill


This paper presents an efficient way of designing Linear Phase Finite Impulse Response (FIR) Filter using hybrid Differential Evolution (DE) and Biogeography based optimization (BBO) algorithms. DE is a fast and robust evolutionary algorithm tool for global optimization. On the other hand, BBO uses migration operator to share information among solutions. FIR filter of order 20 is designed using fitness function that is based on minimization of maximum ripples in pass band and stop band of the filter response. The result obtained from Differential Evolution Biogeography Based Optimization (DEBBO) for the FIR low pass filter is good in convergence speed and solution quality in terms of pass band ripple, stop band ripple, transition width.

Keywords: DE, BBO, DEBBO, Convergence, FIR Filter.
