The question of which spectrally shaped dither signals are appropriate for use in quantizing systems, with and without noise shaping error feedback, or in recursive digital filters using dithered quantization at the output, is addressed. It is shown that dithers that are acceptable without feedback present may be unacceptable if feedback is introduced. In each case, certain classes of dither generators are shown to be appropriate for audio applications.
