3–3
Figure 3–4 depicts signals out of phase with unequal amplitudes. The figure on
the left shows a signal in which the X channel amplitude is greater than the Y
channel. The figure on the right depicts a signal with a larger Y channel
amplitude.

Figure 3–5 depicts an input audio signal in which the X and Y channels are
reversed (reversed polarity) with equal amplitudes.

If the phase error between the X and Y channels is exactly 90 degrees and the
amplitudes are equal, the pattern of the audio signal input is a circle. See
Figure 3–6.
