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 ...

WebThe random or non-deterministic signal is a signal which can only be represented in probabilistic expression rather than its full mathematical expression. Every signal that has some kind of uncertainty is a random signal. Noise signal is the best example of the random signal. Generally, every message signal is a random signal because we are ...

WebThere may be non-deterministic algorithms that run on a deterministic machine, for example, an algorithm that relies on random choices. Generally, for such random choices, one uses a pseudorandom number generator, but one may also use some external physical process, such as the last digits of the time given by the computer clock. WebReal and Complex Signals. Deterministic and Random Signals. Even and Odd Signals. Continuous-Time Signals# A signal \(x(t)\) is a continuous-time (CT) signal if \(t\) is a continuous variable. For an example of a continuous-time signal, please see Fig. 10. Fig. 10 Graphical representation of a continuous-time signal # Discrete-Time Signals# WebAug 31, 2024 · This section will provide you with the tools to put all theory into practice when dealing with random signals. The link between random variables and discrete-time signals is stated and all statistical characteristics of a signal are covered. ...
