Abstract
A digital data signal such as a digitized audio signal is time division multiplexed with a digital dither signal to provide a multiplex signal compound of the digital dither signal and a digital data/dither signal, the latter being an addition of the digital data and dither signals. Then the multiplex signal is converted from digital to analog form by one and the same digital to analog converter. The subsequent removal of the analog dither signal from the analog data/dither signal provides an analog data signal as a replica of the digital data signal. The use of the same converter for the conversion of both dither signal and data/dither signal from digital to analog form makes possible the maximum possible removal of the dither from the analog data/dither signal.
