A Hybrid Differential Evolution Method for the Design of High Pass Digital Fir Filter
نویسنده
چکیده
This paper introduces a stochastic evolutionary algorithm known as hybrid Differential Evolution (DE) for the design of digital High pass FIR filter. It combines the features of both the basic DE and exploratory move for the fine tuning of DE parameters locally as well as globally in the promising search area. A multi-objective function having different performance requirements of minimum magnitude error and minimum pass band and stop band ripples is created to obtain the desired high pass digital FIR filter as close as possible to the ideal FIR filter. From the simulation results, it is confirmed that the proposed algorithm gives more accurate and better results. Keywords— Digital Signal Processing (DSP), Finite Impulse Response (FIR) Filter, Differential Evolution (DE), exploratory move
