The above article [1] omitted a crucial step: A phase unwrapping process for $\angle {{s}_{D.\text{mea}}}[ n ]$ to prevent unnecessary spikes in its derivative, $d\{ {\angle {{s}_{D.\text{mea}}}[ n ]} \}/dn$, as given in (12a), (13a), and (14) and plots on Fig. 5. Additionally, the y-axis of the upper plot in Fig. 5 represents phase difference, not the phase.
