Wannamaker, R.A., and S.P. Lipshitz, "Time Domain Behavior of Dithered Quantizers," presented at the 93rd Convention of the Audio Engineering Society, San Francisco, CA (Oct. 1992). Preprint No. 3418.


Analysis of a quantizing system using triangular-pdf dither has proven that the mean and variance of the total error are constant and independent of the system input. It has been suggested that, for purposes of real-time moment estimation, the nature of the error in such systems is nevertheless essentially different from that of an independent noise source. This hypothesis is investigated both theoretically and experimentally in this paper, and it is shown that their behaviors are equivalent for purposes of estimating psycho-acoustically meaningful statistical quantities.
