20810199 - DIGITAL ELECTRONICS

The course introduces the fundamentals of digital electronics.
The principle of operation and the characteristics of basic digital electronic devices such as inverters, logic gates and flip-flops, will be illustrated before moving to more complex digital devices.
The course provides the main tools for the analysis and design of combinational and sequential logic digital circuits.
The fundamentals of analog to digital and digital to analog conversion will be discussed.

Type of evaluation

Students are evaluated with two alternative modalities (each student can choose their preferred evaluation method): a. Two intermediate written tests and one final oral exam. Each test is evaluated on a 0-30 scale; a mark equal or greater than 18 is required to access the next tests. Final evaluation accounts for the marks obtained in both the written and oral tests. b. One written exam and one oral exam. The written exam is evaluated on a 0-30 scale; a mark equal or grater than 18 is required to access the oral exam. Final evaluation accounts for the marks obtained in both the written and oral exams.
