Front Delay Based Causality for Network Parameters
In the present work different methods for delay causality checking and/or enforcing are described. Group delay, phase delay and front delay concepts are discussed and front delay usage for causality checking is suggested. Front delay is approximated as a minimum of a phase delay in the given frequency range for band-limited transfer function. Since measured data usually misses DC values, simple and accurate method for DC extrapolation is offered.
