TSDT14 Signal Theory

Course Program Autumn 2017

Examination

The examinationen consists of two parts, that are reported separately to LADOK:

  • TEN1 (4 hp), which is a traditional written exam, and
  • LAB1 (2 hp), which consists of four lab assignments which is examined with a report.

For detailed information about the connection between the course aims and the examination, see the following page.

5.1 Written Exam (TEN1)

The written exam consists of two parts. First, there is a task with three simple subtasks that examine the following aims:

  • be able to clearly define central concepts regarding stochastic processes, using own words.
  • be able to reliably perform standard calculations regarding stochastic processes, e.g. LTI filtering (both time continuous and time discrete), sampling and pulse amplitude modulation.
  • be able to reliably perform standard calculations regarding stochastic processes being exposed to certain momentary non-linearities that are common in telecommunication, especially uniform quantization and monomial non-linearities of low degrees.

At least two of these three subtasks have to be solved correctly as a partial fulfillment to pass the written exam.

Then there are five tasks that are graded. Those tasks examine the following aim:

  • with some reliability be able to solve problems that demand integration of knowledge from different parts of the course.

The degree of difficulty of those tasks is as the most extensive tasks in the problem material. The solutions are given at most 5 points per task, i.e. you can at most get 25 points. Grading limits:

  • Grade 3 (pass): 10 points
  • Grade 4: 15 points
  • Grade 5: 20 points

The grade given for the exam is also the final grade for the course when both the written exam and the laborations are passed.

Allowed aids on the written exams:

  • Olofsson: Tables and Formulas for Signal Theory.
  • All kinds of pocket calculators, with empty memory.
  • A German 10-Mark note of the fourth series (1991-2001).
5.2 Laborations (LAB1)

The laborations are based on the Lab-Memo Time-Discrete Stochastic Signals, that you can download from the course webpages. The laborations examine the aims

  • be able to account for the connection between different concepts in the course in a structured way using adequate terminology.
  • be able to estimate the auto correlation function and power spectral density of a stochastic process based on a realization of the process. Also, clearly and logically account for those estimations and conclusions that can be drawn from them.

The laborations consist of the following four tasks:

  • Study 1: Modelling Signals
  • Study 2: Improving Spectrum Estimates
  • Study 3: Non-LTI-Systems
  • Study 4: Special Operations

Those tasks are solved in groups of two students, either on their own or at the scheduled lab occations. We recommend the latter. Each group is allowed to sign up for one two-hour occation per study. You can expect that you need to do additional work on your own to finish the labs.

You pass the laborations based on a report that is sent in to the examiner Mikael Olofsson, as a PDF document by email to

The lab report should be sent in no later than the last day in the exam period in October. Any additional details can be provided during HT2. Please include the course code TSDT14 and your LiU IDs in the filename. That simplifies our work.
