Abstract
The addition and removal of a dither signal takes place by generation of a first signal (102) and a second signal (104) by a first signal source (151) and a second signal source (152). A dither generator (103) is provided that generates a dither signal (106) that is added to the first signal (102) and subtracted from the second signal (104). The first signal (102) with dither added, and the second signal (104) with dither subtracted enter respective Digital to Analog Converters (DACs) (109, 111) and are converted to analog signal equivalents. Finally, the respective analog signal equivalents are summed together to form a composite signal with the dither signal (106) substantially eliminated.
