  ways loudspeaker filters. Functional simulation with xcos (scilab) Application to low volt systems in networking, integrated systems (CPU, micro-electronics)

Compétences requises

Calculation of complex numbers, first order differential equations

Compétences visées

Understanding the basics of electricity, amplifiers, filters

Modalités d'organisation et de suivi

Didier Demigny (Uni. Rennes 1) is in charge of this teaching unit and he will teach the 12 hrs lecture courses
This course covers 2 parts: on the one hand, the measurement of the characteristics and performance of quadrupole amplifier chains, possibly including filters, and on the other hand, the use of complex modelling to study the frequency behavior of electrical circuits or filter functional blocks. The construction and operation of Bode diagrams, the functional study of 1st and 2nd order filters are at the heart of this second part. The exercises are coupled with practical exercises (preparation, interpretation) and also functional simulation (scilab) to reinforce learning.
