Abstract
According to some embodiments, a method implemented in electronic circuitry includes: receiving a first signal having a sinusoidal waveform; receiving a second signal having a sinusoidal waveform; generating a composite signal responsive to the first and second signals; determining an orthogonality adjustment coefficient based on a duty cycle of the composite signal; and applying the orthogonality adjustment coefficient to generate an adjusted second signal that is substantially orthogonal to the first signal.
