What is a random variable and random process?
A random variable is a function X(e) that maps the set of ex- periment outcomes to the set of numbers. • A random process is a rule that maps every outcome e of an experiment to a function X(t, e).
What is random variable process?
Random Variables: In most applications, a random variable can be thought of as a variable that depends on a random process. Examples: 1. Toss a die and look at what number is on the side that lands up. • Tossing the die is an example of a random process; • The number on top is the value of the random variable.
What is a random process when do you say a random process is a random variable?
A random process at a given time is a random variable and, in general, the characteristics of this random variable depend on the time at which the random process is sampled. A random process X(t) is said to be stationary or strict-sense stationary if the pdf of any set of samples does not vary with time.
