Signals and Systems 2

The course is a follow-up of Signals and Systems I. It provides the foundations of analysis methods for continuous time systems in the frequency and complex frequency domains. Furthermore, it presents various system description methods and establishes the connections between these representations. It also deals with analysis methods of discrete time signals and systems both in time, frequency and z domains. The link between continuous and discrete systems is presented by dealing with discrete approximation of continuous time systems, and the basics of signal sampling and reconstruction are shown. The last part introduces analysis techniques for continuous time nonlinear circuits and systems.

3 hours lecture and 3 hours practice

Calculus, basics of linear algebra and matrix algebra, complex numbers, first-order differential equations

Requirements: During the term: (1) Every participant obtains a 3-part homework assignment on the third week. The homework must be completed without assistance. Turn-in weeks are as indicated on the cover page. The solutions will be graded 0...5 points for each part. Zero points will be awarded for late turn-in or missed turn-in. (2) Three small written tests are held for 0...5 points each. Missed tests cannot be supplemented.   (3) One midterm test is held, where 0...25 points can be earned. (4) The general university rules apply for course attendance. The participant will be admitted to the exam iff the following achievements are completed: Sum the point values of the two best small tests (test1, test2), the average value of the two best homework parts (hw) and the midterm points (md): pv = (test1 + test2 + hw + md). The student obtains the signature for admission to the exam if pv is at least 20 AND at least 10 points were obtained for the midterm test. Exam: (1) Admission the the exam is only possible if the signature has been obtained during the semester. (2) The exam consist of written and oral parts. A maximum of 60 points can be awarded in the written test (pe).  The written part is graded as follows: up to 29 points: 1, from 30 points: 2, from 39 points: 3, from 45 points: 4, from 51 points: 5. Participants who have obtained at least a grade of 2 participate in the oral exam part. The final exam grade is being decided by the examiner, taking into account the grade obtained during the written part (in most cases, a +/- 1 grade correction is customary, however, deviations are possible in some cases).  Preliminary exam: N/A  Additional possibilities: An opportunity of a supplementary mid-semester test is provided in case of an unsuccessful mid-semester test in the term period. It is not possible to recap the other mid-term requirements.
