The exam will be written for both parts. Each part can be taken independently. Oral part are optional, according to the rules described below, separately on the two parts of the Course.
The exam for the part on Digital Transmission is based on:
- 2-3 numerical exercises, similar to those that will be solved during the course.
- 2-3 theoretical questions, requiring a free-text answer.
The exam will last two hours and it will be scored on a full scale up to 30. The evaluation of the written exam is based on the correct development of the proposed exercises from the description of the symbolic-formula solutions up to the numerical results. The theoretical questions will be judged according to the completeness of the answers, but also on the ability of the students to reply in a concise way.
This written exam is a “closed-book exam”. During the written exam the student can use only:
• A pocket calculator (NO laptop, tablets etc. Any type of cellphone should be switched OFF)
• A 4 pages (max) summary of formulas written by the student herself/himself (4 pages total, meaning 2 sheets if one writes on the front and back of each sheet)
• Optionally, the tables of numerical values for the erfc function and of Fourier transforms
• No other technical material is allowed (thus no books, handouts, old exercises, etc)
The students who will get a score above 15/30 at the written exam can ask for an optional oral exam, where the questions will mostly regard the theoretical aspects of the course. The optional oral exam is always organized a few days after the written exams. It gives rise to -3 to +3 points that are added to the result of the written exam.
The written exam on the Digital Transmission part proposes exercises that allows to judge if the student knows the topic of the course and is able to apply this knowledge to solve some simplified design examples on modern digital transmission systems. The open questions allows to judge if the student has acquired the most relevant theoretical topic of the course. During the written exam, the students will be allowed to carry with them a pocket calculator, paper and pen and two pages of formulas written by themselves. No other material will be allowed (such as laptops, handouts, etc).

Both parts must be passed with >= 18 grade to able to pass the exam. The final grade will be obtained by averaging the grades of both parts.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
