Abstract
An electronics circuit for accurately digitizing an analog audio, video or ike data signal into a fourteen bit digital equivalent signal/words having thirteen data bits and a sign bit and then introducing a dither component into the digital equivalent signal. The circuit includes a first Electrical Erasable Programmed Read Only Memory which generates a dither component to be added to a selected, five, six, seven or eight bits of each fourteen bit digital equivalent sample. The circuit also includes an automatic gain control circuit and a data selector circuit which, in combination, select the five, six, seven or eight data bits of the thirteen data bits of each digital equivalent sample to supply to a binary adder. The binary adder then adds the dither component to the selected data bits of each digital equivalent sample. The five, six, seven or eight selected bits of each fourteen bit sample provide optimum video, audio or like information for the sample.
