摘要:
In an analog-digital converter, a sine signal angle-modulated with noise or pseudonoise is used as a dither signal. The dither signal is superposed on an analog useful signal that is to be digitized. This signal is then digitized. The dither signal is then filtered out to produce the digitized useful signal.
