Realization of the All-Pole Third-Order Transfer Function

Realization possibilities of the all-pole third-order transfer functions are discussed. For this purpose, the ladder network with controlled voltage source in any shunt branch is used. The voltage source is controlled by shunt branch voltage. The transfer functions are expressed with cumulants. Because of high degree of symmetry, there are the rules for cumulant development. In this paper, the controlled voltage source with controlling voltage placed in shunt branch behind source is considered. In that case, the transfer function contains only poles. The realization of the all-pole third-order transfer function is given on example. The transfer function stability is analyzed using the Routh-Hurwitz criterion for the third degree polynomials.
