MA1254    RANDOM PROCESSES                        3  1  0  100

AIM
This course aims at providing the necessary basic concepts in random processes. A knowledge of fundamentals and applications of phenomena will greatly help in the understanding of topics such a estimation and detection, pattern recognition, voice and image processing networking and queuing.

OBJECTIVES
At the end of the course, the students would
•    Have a fundamental knowledge of the basic probability concepts.
•    Have a well – founded knowledge of standard distributions which can describe real life phenomena.
•    Acquire skills in handling situations involving more than one random variable and functions of random variables.
•    Understand and characterize phenomena which evolve with
respect to time in probabilistic manner.
•    Be able to analyze the response of random inputs to linear time invariant systems.
