In this first video of the Statistical Signal Processing part of the
PETARS course, the notion of random signals, or stochastic processes is
introduced. It is defined as a natural extension to the conceptual
development of random variables and random vectors, but where a
deterministic signal is associated with each outcome of the experiment.
After a formal definition of the random process, the notion of an
ensemble of realisations is considered. The video then gives an example
of plotting an ensemble for a particular problem. The random process is
also considered as a sequence of random variables, where the random
variables have dependences. Finally, this video discusses the general
concepts regarding analysing random processes that will be considered in
the remainder of the course.
