However, such a system (under mild assumptions) can also be represented by transfer functions in a port characterization, frequently referred to as a chain-scattering representation. Due to its cascade properties, the chain-scattering representation is used throughout many fields of engineering. This paper studies the relationship between poles and zeros of input-output and chain-scattering representations of the same system.Keywords: Computer science; Chain-scattering systems; Input-output systems; Two-port networks; Zeros; Transfer functions Chain-scattering systems; Input-output systems; Poles; Two-port networks; Zeros200610.1016/j.sysconle.2005.08.0072015-12-07
