Knyshev I. Theory of analogous-digital signal transformations and error evaluation

Thesis is dedicated to unification of requirements and development of unified analysis system of temporal discretisation processes and amplitude signal oscilla-tion, and also evaluation of appearing errors. This worksystematizes requirements for ideal discretisation (theorems by Kotelnikov) and defines necessary phase correlaрtion between a signal and discretising consistency. Unification conditions for Kotelnikov theorems for ampli-tude quantuming are formulated, ideal quantumer Іrequirements signal and restoring device requirements are set forth. The work introduces integral and differential function of distribution for levels for determi- nated signals, allowing usage of probabilistic analysis and optimization methods. The thesis shows expressions,connecting temporal discretisation intervals with each other, with ratio signal/noise.
