Course Director

TSTE06 Digital Filters (6hp) is a course that covers the basics of the design and implementation of digital filters. It covers the following topics: Discrete-time and digital signals and systems. DSP-algorithms. Approximation theory including Butterworth-, Chebyshev-I-, Chebyshev-II-, and Cauer-approximations. Frequency transformations. Synthesis and realization of IIR- and FIR-filters, in particular wave digital filters. Systems with multiple sampling frequencies, decimation and interpolation. Finite-wordlength effects. Numerical properties and implementation issues for digital filters. The course covers the same topics as TSEI07 Digital Filters, but at the level A instead of G2.

Laborative work (4x4h = 16h):

Solving filter design and implementation problems using Matlab

Depending on the number of students, there may be a need need to sign up for the labs. Information about this will available when the course has started.

Note that the laborative work is mandatory and must be passed in order to pass the whole course!

Examination

A written exam of 4 hours duration.
Aids for exam: Mathematical tables/formulas and pocket calculator.
Max 70 p, 30 p required to pass.
Optional seminars (oral), two occasions. Active participation gives maximum 10 p (5 + 5) on the written exam, corresponding to Problem 1.
