Abstract
A system and method for improving linearity of data outputted from an analog-to-digital converter and reducing digitization artifacts, is provided. A noise generator is provided for generating noise and adding the noise to at least one code word that is introduced to the system, wherein the at least one code word comprises a unitary portion and a fractional portion, the noise being added to the fractional portion of the at least one code word. A storage device is also located within the system for storing the at least one code word, and a high threshold and a low threshold for each of the at least one code word. The storage device is capable of outputting the high threshold and the low threshold of the at least one code word as a result of receiving the unitary portion of the at least one code word, wherein the low threshold and the high threshold, in combination with the fractional portion, are utilized to derive linear digital data having a uniform resolution.
