Learning outcomes

The student will develop the ability to analytically characterize discrete-time and continuous-time deterministic signals and as well as linear time-invariant systems, both in the time and frequency domains.

• Frequency domain characterization of linear time-invariant continuous-time systems. 19 hours (2 hours in lab)
• Time domain characterization of deterministic continuous-time signals. 4 hours
• Time domain characterization of linear continuous-time r systems. 4 hours
• Analysis of discrete-time signals. 10 hours (2 hours in lab).
  
• Analysis of linear discrete-time systems 6 hours (2 hours in lab).
• Energy signals and power signals. 4 hours.

Teaching methods

Traditional lessons. In addition, laboratory experiences are scheduled dealing with signal characterization, linear time-invariant systems, discrete-time systems, and modulation schemes. These experiences will involve the use of measurement instruments such as an oscilloscope, signal generator, and spectrum analyzer.

In view of the types of activities and teaching methods adopted, attendance of this training activity requires all students to complete Modules 1 and 2 in e-learning mode [https://www.unibo.it/it/servizi-e-opportunita/salute-e-assistenza/salute-e-sicurezza/sicurezza-e-salute-nei-luoghi-di-studio-e-tirocinio] and to participate in Module 3 on health and safety in workplaces. Information on the dates and procedures for attending Module 3 can be found in the appropriate section of the Degree programme website.

Assessment methods

The learning assessment is carried out through a final examination, which verifies the expected knowledge and skills through a 2-hour written test followed by an oral examination to be taken before the following call for exam. The written test, during which the use of books and notes is not allowed, consists of 9 questions that, together, can score a maximum of 30 points. To be eligible for the oral examination, a minimum score of 18 points in the written test is required. The oral examination involves in-depth exploration of some of the topics covered during the course. The average duration of the oral examination is 30 minutes. The final grade is determined based on a combined evaluation of the written test and the oral examination, with the possibility of adding up to 5 points to the score achieved in the written test.

Teaching tools

Personal computer, hardware laboratory equipped with function generators, oscilloscopes and spectrum analyzer.
