Content : After some generalities on physical systems, we focus on the notion of transmittance or transfer function of linear systems. The study of the frequency response is used to introduce harmonic BODE representation, widely used in electronics. Using the Laplace transform, presented in mathematics, then allows to generalize the notion of transmittance and to use it to study the transient response in time domain (pulse, step and ramp responses). Aspects of knowledge or behavior models are introduced. The concept of stability is barely touched, opening the way for feed-back system control studied later (S6). This presentation of linear systems is complemented by an introduction to the study of quadrupole, addressing a presentation of the main representative matrices (impedance, admittance, hybrid, transfer), their properties (symmetries, associations), characteristics quantities: input/output impedances, gains, iterative impedance, to finish on the concept of power adaptation which will be detailed in the following semester.
