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