What is a random signal?

Abstract. A random, or stochastic signal is characterised by its lack of predictability. Unlike a deterministic signal whose value at any instant is known, the value of a random signal at any instant is not known and cannot be predicted from a knowledge of values at other past instants.

What is random signal in communication?

The term random signal is used primarily to denote signals, which have a random in its nature source. As an example we can mention the thermal noise, which is created by the random movement of electrons in an electric conductor.

What is deterministic and random signal?

Signals that can be modeled exactly by a mathematical formula are known as deterministic signals. Deterministic signals are not always adequate to model real-world situations. Random signals, on the other hand, cannot be described by a mathematical equation; they are modeled in probabilistic terms.

What are the random signal and random process?

A random process is a collection of time functions or signals corresponding to various outcomes of a random experiment. The random process represents the mathematical model of these random signals. A random process (or stochastic process) is a collection of random variables (functions) indexed by time.
