Phasor impulse can also be viewed in a polar plot, as shown in Figure 8-12. The lower plots
use phasor impulse to show a clear reflection with approximately 180 degrees phase,
indicating a low-impedance mismatch. The upper plots use standard bandpass mode and do
not adequately reveal the phase of the reflection.
