A SPICE method for designing digital filters from analog filters
Corneliu Rusu, Lăcrimioara Grama, Jarmo Takala · 2010
Usually IIR digital filters are designed by using analog filters described in time or transform domain, then by converting the analog filters to digital filters using appropriate transformation from s-domain to z-domain. For many engineers analog filters mean certain circuits or a netlist of components, and digital filters are a set of statements in certain software. In this work, we show how to obtain a digital filter from a given netlist of an analog filter by skipping the transfer function description.
