Abstract

The type of signals that we have been dealing with in the previous chapters are deterministic in nature, i.e., signals which may be described by mathematical expressions and whose behavior does not contain any uncertainty or randomness. Typical examples of deterministic signals are 2 cos(100πt+π/4), u(t - 2), δ(t) - δ(t - 5), e-2tu(t), e-4|t|, etc.
