Abstract: A method, computer program product, and computer system for determining a magnitude and phase of a spurious-free dynamic range component. A first signal and a second signal may be received from a first source operatively connected to a differential component. A first output associated with the first signal and a second output associated with the second signal may be nulled. The first signal and the second signal may be shorted. A second source operatively connected to the differential component may be disconnected. The first signal of the first source may be applied at a same phase as the second source with an additional phase delta, +Y?. A first differential residual signal may be measured using the first signal at the same phase as the second source with the additional phase delta, +Y?. The second signal of the first source may be applied at the same phase as the second source with an additional phase delta, ?Y?.

Abstract: A method, circuit, and computer program product for receiving a first intermediate signal that is at least partially based upon a first reference signal. A second intermediate signal is received that is a time-shifted version of the first intermediate signal. An output signal is generated that is based upon the difference between the first intermediate signal and the second intermediate signal. An anticipated differential change in the output signal is determined, the anticipated differential change to occur based upon a transition in the first reference signal. A realized differential change in the output signal is measured, the realized differential change occurring based upon a transition in the first reference signal. The realized differential change in the output signal is compared to the anticipated differential change in the output signal to determine a nonlinearity indicator.

Abstract: The present disclosure relates to a system and method for mapping system transfer functions. Accordingly, some operations may include receiving a first intermediate signal that is at least partially based upon a first reference signal. A second intermediate signal is received that is at least partially based upon a second reference signal. An output signal is generated that is based upon the difference between the first intermediate signal and the second intermediate signal. A first anticipated differential change in the output signal is determined, the first anticipated differential change to occur based upon a transition in the first reference signal. A second anticipated differential change in the output signal is determined, the second anticipated differential change to occur based upon a transition in the second reference signal. Numerous other operations are also within the scope of the present disclosure.
