Software Based Pole-Zero Extraction Technique for nth Order Analog Filters.

The positions of poles and zeros of a filter circuit indicates how the system behaves with variation in frequency as well as it results a tool to utilize the system gain by setting the frequency range in a complex process. The existing solutions to extract the poles and zeros often include too complex calculations to use it frequently. In this paper we propose a compact tool to detect the position of poles and zeros of any practically designed analog filter of any order without going through the working principle of the circuit as well as by using this technique calculation of transfer function is does not need to do derive which often becomes hectic.
