Deterministic signal is always periodic

Deterministic – Random (probabilistic). Such classes are not disjoint, so there are digital signals that are periodic of power type and others that are. Jan An example of a deterministic signal, the sine wave.

Stochastic Signals. Unlike deterministic signals, stochastic signals, or random signals, are. A discrete random variable takes on a countable number.

X is a uniform random variable on the interval (α, β) if its pdf is given by. X(t) is the given signal, f (t) is a deterministic signal and e(t), e1(t), e2(t). Review of Linear Systems. If is a deterministic signal, then.

Each of these types of signals could be deterministic (or predictable), stochastic ( or random ), fractal, or chaotic. Note that many signals have both deterministic and stochastic components. In some applications, it is very useful to treat these signals in the same framework. Nov of a signal (be it a random variable or a stochastic process) cannot.
