Contents Introduction to probability theory: continuous, discrete and mixed random variables. Probability density functions. Probability distribution functions. Joint random variables. Introduction to stochastic processes: definitions, autocorrelation and autocovariance functions. Fundamentals of stochastic processes.
Reference texts Roy. D. Yates, David J. Goodman, Probability and Stochastic Processes, John Wiley & Sons Inc; 2nd International Edition, 2004.

Handouts by the instructor.
Educational objectives The objective of this module is to provide the students with the knowledge to correctly apply probability theory and measurement theory. At the end of this class the student will have learned:

- the concept of continuous and discrete random variable and its PDF and CDF

- the concept of function of a random variable

- the concept of joint random variables and vector of random variables

- the concept of function of two random variables

- the concept of stochastic process and of its general properties

Moreover, he will be able to:

- solve exercises that require modeling using discrete, continuous and mixed random variables

- solve exercises using the concept of stochastic process
Prerequisites Calculus I is mandatory. Students must also be able to perform simple mathematical modeling in two dimensions and capable to solve simple double integrals.
Teaching methods Frontal lectures at the blackboard. Students are expected to provide active participation and show autonomous study capabilities. Proficiency in solving exercises can only be developed by complementing attendance of lectures with dedicated sessions in the solution of exercises at home.

Learning verification modality Written and oral tests. The written test requires solving two exercises (7 and 8 points each) and in answering 15 quizzes with 4 possible answers, of which only one is the correct one.
To each correct quiz answer 1 point is assigned. Wrong answers results in minus half a point. The oral examination covers all course content program and consists both in questions about the theory and in the solution of exercises. Its lenght is about 20-25 minutes. The final grade is based on both grades in the written and oral examinations.
