http://generation-g.ning.com/photo/albums/butterworth-filter-matlab-pdf-code WebJan 6, 2024 · The proposed IIR design is realized by parallel–pipeline-based finite impulse response (FIR) filter. The FIR filters have excellent characteristics such as high stability, linear phase response and fewer finite precision errors. Hence, FIR-based IIR design is more attractive and selective in signal processing.
