Abstract

Noise that is normally generated during the switching of a noise shaper may be reduced by switching the noise shaper to an inactive or off state after the occurrence of one or more predetermined criteria, for example the detection of a predetermined number of data values below a threshold value or equal to a certain value, or of a predetermined number of data values within a threshold region about a value that is constant with respect to the data values.
