Subject fundamentals
The course aims at completing the students' education in basic mathematics, by introducing the theory of analytic functions, distributions, Fourier and Laplace transforms, and discrete and continuous probability. Such topics play an essential role in engineering applications. Examples and motivation will be drawn from problems in electronic and telecommunication engineering and physics, offering further insights.

Expected learning outcomes
a) Knowledge and understanding
Students are taught some basic mathematical notions and tools for solving various problems ranging from signals analysis to the study of random phenomena. The theory of distributions provides a general language which enables to deal with signals arising in impulsive or discontinuous phenomena: this theory is the natural setting for the study of the Fourier and Laplace transforms. Students learn the techniques for the computation of the transforms of the main distributions: delta Dirac, Dirac comb, and piecewise regular functions included. Complex analysis is the proper setting for the theory of the Laplace transform and is the advanced tool for the analysis of singular phenomena and for the computation of integrals. Moreover, students are provided with the main probabilistic tools necessary for solving problems under uncertainty. They learn how to deal with random phenomena and with the variables involved in them. b) Applying knowledge and understanding At the end of the course students will be able to apply the analytical techniques required for the analysis of the signals of any nature (impulsive, erratic, etc.). Also, they will be expected to have acquired the skills to evaluate the probability of outcomes and extrapolate information useful in solving problems in electronic and telecommunication engineering. The ability to apply the gained knowledge will be verified through class exercises. 
Prerequisites / Assumed knowledge

Delivery modes
Exercises will cover the topics of the lectures. Some of them will be carried out by the teacher at the blackboard, others will actively involve the students.

Texts, readings, handouts and other learning resources
Lecture notes and slides will be available in the course web page.
For probability the reference textbook is: Ross, S. 'A first course in probability', Pearson Ed. Int., (8th ed., 2010). 
Assessment and grading criteria
Two hours written exam composed of two parts:
1. Multiple choice test. The necessary condition to pass the exam is to correctly answer to at least 5 out of the 10 questions of the multiple choice test. Any correct answer scores 1 point. 2. Exercises composed of different questions. The score for the exercises is 22 points.
