The aim of this course is to provide the fundamentals of electronic design in terms of both synthesis and analysis methodologies. The course is focused on electronic system architecture for the processing of signals coming from and directed to output stages, after suitable analog to digital (A/D) and digital to analog (D/A) conversion. Particular attention will be dedicated to the analysis of front-end electronics and signal conditioning (amplification and, filtering), as well as frequency stability. Aim of the course also includes the definition of design specifications, both DC and AC, distortion and noise, as well as A/D and D/A conversion techniques. The course will be completed by a detailed analysis of a set of projects with applications in consumer electronics, telecommunications, industrial and medical electronics.
