- To provide students the tools needed to analyse systems involving random signals.
- To improve their skills in analyzing random phenomena which occur in Electrical Engineering application.
Course Outcomes
At the end of the course, students will be able to <br />1. Understand the axiomatic formulation of modern Probability Theory and think of random variables as an intrinsic need for the analysis of random phenomena. <br />2. Characterize probability models and function of random variables based on single & multiples random variables. <br />3. Evaluate and apply moments & characteristic functions and understand the concept of inequalities and probabilistic limits. <br />4. Understand the concept of random processes and determine covariance and spectral density of stationary random processes. <br />5. Demonstrate the specific applications to Poisson and Gaussian processes and representation of low pass and band pass noise models.
