Signal Delay

The origin of the various types of delay and their meaning in communications is briefly discussed. Signal delay is defined by means of a cross correlation function which also serves as the conditional equation. The derivation of signal delay, which is to be understood as a generalized phase delay, becomes possible by splitting the delay into two additive contributions. One of them can be understood as a generalized group delay, the other is attributable to "intercept distortion" and can often be neglected.
