Systems and methods are provided that allow for accurate computation of the group delay and, if desired, phase response of an electrical network from known amplitude measurements. In one embodiment, a model that includes information regarding locations (e.g., approximate locations) of at least one of poles and zeros for an electrical network is used for computing at least one of group delay and phase response of the electrical network for a frequency range over which amplitude measurement data is unknown. Further, a transition segment may be determined for use in computing contribution to group delay over a transition between a first frequency region for which amplitude measurement data is known and a second frequency region for which amplitude measurement data is unknown. The techniques provided may be used for analyzing various types of systems, such as lowpass, bandpass, etc., and may be applied for analysis of non-minimum phase electrical networks.
