  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.
