Wannamaker, R.A., and S.P. Lipshitz, "Dithered Quantizers With and Without Feedback,"
Proc. of the 1993 IEEE Workshop on Applications of Signal Processing to Audio
and Acoustics, New Paltz, NY, 1993 Oct.
It is shown that quantizing systems without feedback respond to the
use of particular spectrally-shaped dither signals quite differently
from those with feedback paths. For each type of system, conditions
are given which ensure that the quantization error will be wide-sense
stationary with no input dependence and with a predictable power
spectral density function.
