Hence the value is predictable for arbitrary times

This preview shows page 11 - 14 out of 14 pages.

Hence, the value is predictable for arbitrary times and can be reproduced identically arbitrarily often. 11 Probabilistic Signal Has only probabilistic representation such as mean value, root mean square and etc Also known as random signal The value of the signal cannot be predicted accurately E.g. noise in communication system
