Abstract
Calibrating a plurality of digital-to-analog converters using a calibration memory for storing calibration characteristics for respective digital-to-analog converters so as to provide uniform analog responses to digital data, and a calibrator to receive original digital data and to adjust it utilizing the stored calibration characteristics to produce adjusted digital data that, when inputted into a digital-to-analog converter, produce an analog signal that corresponds to the original digital data.
