Figure 3–2: X and Y signal in phase with equal amplitudes
Figure 3–3 depicts an input audio signal in which the X and Y channels are out
of phase by some amount but have equal amplitudes. The pattern is an ellipse
rather than an line, which indicates the signals are out of phase. The axis of the
ellipse lies terminates in the target boxes, which indicates that the amplitudes are
equal.
