As in the case of a random variable, a random process can be defined using a random experiment. Remember that a random variable is obtained by assigning numbers on x-axis to all possible outcomes of s i . However, if instead of numbers, time functions x(t, s i ) are assigned to the outcomes of s i from a sample space S, we obtain a random process X(t, s), as shown in Fig. 6.1.
