12.3.1.3 Deterministic and Random Signals
Deterministic signals are those signals which can be represented by mathematical
expression and such kind of signals are well determined at any point of time. Sine,
cosine, and exponential signals are examples of deterministic signals. Figure 12.15
shows an example of a deterministic signal.
On the other hand, random signals are nondeterministic signals which include
uncertainty in the signal values at some point of time. For representation of such
kind of signals instead of mathematical representation, they require probabilistic
models. Random noise is an example of random signal. Figure 12.16 shows a
random noise generated in Matlab.
