5.7.1.3 Quadrature Offset
Changes the phase angle between the I and the Q vectors from the ideal 90 degrees,
while the amplitudes are maintained. A positive quadrature offset results in a phase
angle greater than 90 degrees. The effect of a positive quadrature offset in the I/Q con-
stellation diagram is shown on Figure 5-16.
