Abstract
A system for determining the s-plane parameters, s.sub.i and r.sub.i, of the transient response, ##EQU1## of a network-under-test (NUT). A filter bank, including N serially connected filter elements, has an input port and N output ports being the output ports of the filter elements. The system includes circuitry for sampling the response signal, at the N filter bank output ports. T seconds after a transient signal is received at the input port. A processor utilizes the values of the sampled response signal to determine the values of s.sub.i and r.sub.i.
