Deterministic and random signals examples
Webcourse. Properties and representations of deterministic signals and systems are reviewed and elaborated on, including group delay and the structure and behavior of state-space models. The text also introduces and interprets correlation functions and power spectral densities for describing and processing random signals. Websignal is called digital. It is written as: s(n) = s(n∆). Some signals occur naturally at discrete times without analog to digital conversion, such as warehouse inventories, daily stock market prices. A transform maps a discrete signal to another. A related concept is discrete-time system that maps an input signal to an output signal by a set ...

WebFig. 1.7 shows examples of correlation functions and frequency spectra of various types of signals: random and periodic. The periodic signal is a special case of the generalized transform pair, Eqs. (1.33) and (1.34a); the correlation of such functions is also periodic, e.g., Eq. (1.16). We can see this more clearly by the following derivation. Web2 Deterministic signals are preferable because for analysis and processing of signals we can use mathematical model of the signal. Not Preferable. The random signals can be described with the help of their statistical properties. 3 The value of the deterministic signal can be evaluated at time (past, present or future) without certainty. The ...

Web1.2 Deterministic and Non-deterministic Random Processes A random process is called deterministic if future values of a random process can be per-fectly predicted from past values. If a process does not have this property it is called non-deterministic. Example: A random process over time is defined as X(t) = Acos(ω0t+Θ)
