Abstract
An apparatus and method produce a plurality of output signals (917-921) with fixed phase relationships therebetween. The apparatus (900) includes a first signal generator (901), a second signal generator (903), and a signal processor (907). The first signal generator produces a first input signal (911) at a first frequency. The second signal generator produces a second input signal (915) at a second frequency, wherein the second frequency is an integer multiple of the first frequency. The signal processor receives the first and second input signals and produces a plurality of output signals (917-921) having fixed phase relationships therebetween at the first frequency, wherein the fixed phase relationships are based on the integer multiple and wherein each of the output signals has a single, determinate phase relative to the phase of the first input signal.
