Digital signal processing requires two discretization operations on analog signals, one in time called sampling. and one in amplitudę called quantization. Ironically, although both operations are deterministic, the engineering community has historically approached the second operation only by probabilistic modeling. While this approach has been satisfactory for traditional data acquisition, it is becoming insufficient foradvanced techniques of analog-to-digital conversion such as Sigma-Delta modulation, which are capable of conversions of high resolutions under analog Circuit imperfections. The lack of signal theory applicable to amplitudę quantization has limited engineers to empirical and heuristic modeling.
The goal of this lecture is to revisit power spectral analysis from its introduction by Wiener, and construct what has been missing to perform the spectral analysis of quantization in its original deterministic naturę. The most challenging part is how white noise can be deterministically realized. in theory and in practice.
