the dynamic range of the signal itself. A typical application may be a full- range DSP volume control, where e.g. a 16 bit input is modified by a gain control function and passed out to a DAC of 18 or 20 bits. In these cases:

∙If the programme material permits, use pre-emphasis

∙Use Shape A or high-pass dither.
