The application of multi-criterion satisfactory optimization in FIR digital filter design

The paper presents a new approach, which uses multi-criterion satisfactory optimization (MCSO) in digital filter design. We use the frequency-sampling method in finite impulse response (FIR) digital filter design, and use multi-criterion satisfactory optimization to optimize the unspecified frequency samples occurring in the transition bands. The results show that our method is useful for FIR digital filter design.
