12 results about "Digital reproduction" patented technology

Digital reproduction is one form of data reproduction which is based on the digital data model. The advantage of digital reproduction of data over analogue reproduction is its lossless quality. Reproducing analogue data is inherently lossy, because every (electronic) component involved in any analogue reproduction process can introduce noise to the final result.
