Group delay is a property of a device or a system: a plot of the change in phase of the response as a function of frequency; it is the negative derivative (slope) of the phase-vs-frequency
Contains two triangle waves. Both are 24-bit with 16,384 samples and contain one cycle of a triangle wave. One has a frequency of 1.0 Hz and is sampled at 16.384 kHz. The other has a frequency of
