Figure 10. This Plot Gathers the Real and Imaginary Portions of the Feedback
Signal Collected when the Fast and Slow Lanes are Separately ac Swept
Once we reached that point, we can apply Equationsꢀ8
andꢀ9 via the graphical viewer internal script. The resulting
waveforms are displayed on Figures 11 and 12 then
compared to Figure 7. They are identical gain wise
(Figureꢀ11), despite different signs on the phase in Figureꢀ12
-1
(the tan function is modulo 180°).
