Answer by Dan Boschen for What is meant by "Group delay" in simple words?
Here is my simplest explanation:The group delay, as the negative derivative of phase, predicts the time delay of the amplitude envelope of a pulse, as shown in the hand-drawn graphic below. The upper...

It stems from the definition of the Laplace/fourier transforms using $e^{-st}$ or $e^{-j\omega t}$. This can be checked intuitively by looking at the transform pair of a delayed impulse, compare the...
