ABSTRACT:
By means of a controlled integrator, a noise component in the residual signal which is left after a conversion cycle of an analogue-to-digital converter can be eliminated for the major part. It is then possible to digitize this residual signal and thus to obtain additional bit information, as a result of which the range and the resolving power of the analogue-to-digital converter are increased.
