  • Determining and compensating respective harmonic distortions of digital to analog and analog to digital conversions
    Patent number: 11283458
    Abstract: A method and an apparatus for determining and compensating respective harmonic distortions of digital to analog and analog to digital conversions are described. A signal from a digital to analog converter is passed through a plurality of calibration paths. Output signals from each calibration path, converted by an analog to digital converter, are analyzed in order to determine the harmonic distortions introduced by each side of the chain separately. One embodiment represents a digital sine generator which has harmonic distortions of its analog output continually compensated. Another embodiment compensates harmonic distortions introduced by an analog to digital converter in order to measure harmonic distortions of an analog signal precisely. Other embodiments are described and shown.
