Abstract:
1. A computer-implemented method for determining a magnitude and phase of a distortion component comprising: receiving, by a computing device, a first signal and a second signal from a first source operatively connected to a differential component; nulling a first output associated with the first signal and a second output associated with the second signal; shorting the first signal and the second signal; disconnecting a second source operatively connected to the differential component; applying the first signal of the first source at a same phase as the second source with an additional phase delta, +Y measuring a first differential residual signal using the first signal at the same phase as the second source with the additional phase delta, +Y applying the second signal of the first source at the same phase as the second source with an additional phase delta, −Y measuring a second differential residual signal using the second signal at the same phase as the second source with the additional phase delta −Y determining the magnitude and phase of the distortion component of the first source based upon, at least in part, the first and second differential residual signal.
