Learning Outcomes AAv (AAv) ​

  • AAv1 [heures: 15, B2] (Study of electronic circuits of order 2): At the end of the 4th semester of electronics, the student will be able to determine in analytical or numerical form the characteristic parameters of a circuit of the 2nd order according to the value of its components by first determining its transfer function.

  • AAv2 [heures: 30, B3, C3, D3] (Modeling and representations of order 1 and 2 LTI systems): At the end of the 4th semester of electronics, the student will be able to determine, for an LTI system describes in a given formalism, the index and frequency response using the resolution of the differential equation or the Laplace transform, and to represent these responses in appropriate form.

  • AAv3 [heures: 25, D3] (Characterization and identification): At the end of the 4th semester of electronics, the student will be able to characterize the behavior of an LTI system represented by its index response, its frequency response or its diagram of poles and zeros.

  • AAv4 [heures: 30, B1, B3, C2, C3, D3, F1] (Design): At the end of the 4th semester of electronics, the student will be able to propose a circuit respecting specifications. The specifications will be specified in the form either of several parameters characteristic of a cell of order 2 (type, amplification coefficient, natural frequency, damping coefficient) or by a frequency template. The student will be able to check the conformity of his proposal with the specifications using simulation software (Python/Numpy/Scipy and LTspice).
