State-space approach for symbolic analysis of an analog passive filter and its conversion to digital filter

Abstract

The conversion of an analog filter described by a wiring diagram into another digital filter, having the same frequency characteristics was recently solved by a Python implementation. In this paper we will use this application for symbolic analysis of a passive filter having multiple components. Its conversion to digital filter is also described. Through experimental results we prove that the magnitude and phase characteristics are similar for the active analog filter and for the corresponding digital filter.
