The Exponential, Gaussian and Uniform Truncated Discrete Density Functions for Discrete Time Systems Analysis
Author:
Abstract: Continuous density functions and their truncated versions are widely used in engineering practice. However, limited work was dedicated to the theoretical analysis and presentation in closed forms of truncated density functions of discrete random variables. The derivations of exponential, uniform and Gaussian discrete and truncated density functions and related moments, as well as their applications in the theory of discrete time stochastic processes and for the modelling of communication systems, is presented in this paper. Some imprecise solutions and common mistakes in the existing books related to discrete time stochastic signals analysis are presented and rigorous mathematical solutions are offered.
