The course aims at giving students those tools needed to know and understand the fundamental elements by which electronic systems operate in the framework of automotive systems. The goal is not to educate electronic designers, rather to offer a broad basic competence aimed at maximizing the ability to work as a part of interdisciplinary teams also including electronic designers and experts in information technologies.
The goals of the course can be summarized as follows:
Knowledge and understanding: acquisition of basic concepts related to
the typical circuit blocks of an automotive electronic system with
emphasis on digital and microcontroller circuits, signal conditioning
circuits (including operational amplifiers, analog filters), circuits
for analog-to-digital and digital-to-analog conversion, basic
principles of sensors and actuators including those used in the
Applied knowledge and understanding: acquisition of the necessary skills for the use of analytical techniques and development methodologies; acquisition of basic skills in the analysis and design of analog and digital electronic systems.
Making judgements: acquisition of the ability to interpret specifications, even incomplete ones, and provide one's own contribution within interdisciplinary teams that also include electronic designers and information technology experts.
Communication skills: acquisition of skills in presenting designs to specialized and non-specialized individuals.
Learning skills: acquisition of skills necessary to stay updated in the disciplinary field and optimize one's ability to participate effectively within an interdisciplinary work team.

Introduction: sensing, signal conditioning, information processing, actuation. Structure of electronic systems interfaced with mechanical parts. Fundamentals of circuit theory.
The ingredients: basics of electronic devices. Use of transistors as switches and as continuous regulators. Elements on technologies for sensors and actuators.
Digital systems: logic gates; digital signals; combinatorial and sequential networks; logic families; representation of numbers; fundamental function blocks; ALUs and microcontrollers; PLAs and FPGAs.
Analog systems: the operational amplifier, basic filters, techniques for signal conditioning.
Data acquisition and information representation: D/A and A/D conversion.
Time encoding: V/F and F/V conversion; pulse width and pulse density modulations.
Hints on actuation and power conversion: more on continuous regulation and switched mode regulation.
Slight modifications to the course content are possible in relation to the average background knowledge, unexpected situations and in light of students' feedback.
The course will be based on theoretical lectures presented both on the blackboard and using slides. Some lectures will be devoted to exercises, examples, case studies, both at the blackboard and through the use of numerical computation platforms (e.g., Matlab), graphical environment for programming and simulation of multidomain dynamical systems (e.g., Simulink), or circuit level simulators (e.g., Spice. Digital logic designer). The slides used for the course will be made available for the students. The same shall happen for the code used in the examples, the demonstrations and the case studies.
The assessment of the competences acquired by the students is based both on a written test and an oral exam. The written test includes some exercises aimed at evaluating both the understanding of the contents of the course (and specifically of some parts of the course), and the achievement of some practical ability to manage analysis and design tools. The oral exam complements the written test by looking more deeply at theoretical aspects.
By the end of the course, the student shall possess knowledge useful to practice simple forms of signal conditioning, data acquisition, and information processing with specific reference to mechatronics and automotive applications.
Furthermore, he/she shall be trained to read technical documentation, to understand the results of system level and circuit level simulations and to use formalization, notations and merit factors to help his/her activity as part of interdisciplinary design teams comprising experts in information technology and electronics.
