Electronic systems for communications


Programme (detailed contents):

The aim of this course is to present the fundamentals of analog and digital systems used by communication systems designers. The course is organized into 13 parts; the objective is to present typical analog and digital functions of a telecommunication system, such as a mobile phone. Signal processing is presented with a special emphasis on analog filter structures. The study of electronic circuits based on operational amplifiers is done in the linear regime with Laplace transform and then in the saturated regime.

The second part of the course is dedicated to digital electronics concepts: combinational and sequential logic, gates, latches, registers, multiplexors, converters, memories. The link with digital signal processing is made with architectures of analog to digital and digital to analog converters. The problems of communication and interfacing between logic families are analyzed in parallel with such notions as communication

protocols and transfer modes (synchronous, asynchronous, duplex).



16 course sessions, 14 exercise sessions and 7 labs.


Main difficulties for students:

· OA principles and computation of transfer function for electrical circuits based on operational amplifiers

. Design of electronic circuits (choice of components)



At the end of this module, the student will have understood and be able to explain (main concepts):

· Fundamentals of signal processing (amplification, filtering, Fourier transform)

· Ideal operational amplifier (OA) and limitations of real OA

· Basic analog circuits

· Conditions of linear/saturated regime of an OA
