The delivery of new degree courses at the university means that subjects are designed so that students will spend a certain period of study, according to the credits which are assigned. The course Digital Circuits and Systems, which is taught in the first semester of second year degrees of Telecommunication Systems and Telematics Engineering at the EETAC (Escola d’Enginyeria de Telecomunicació i Aeronàutica de Castelldefels), has 6 ECTS, equivalent to about 150 hours of student’s work.
