From bulky analog active filters to digital filters
Alexandru Lodin, Lăcrimioara Grama, Corneliu Rusu · 2018
In this paper we show how a bulky analog active filter, described only by its circuit diagram, can be converted to the corresponding digital filter, having the same frequency gain and phase characteristics. The state-space based approach has been implemented using Python high-level programming language. Experimental results are also presented.
