1. Prerequisites

At the start of this course the student should have acquired the following competences:

  • Competences corresponding the final attainment level of secondary school

An active knowlegde of :
  • Dutch
  • English
  • General knowledge of the use of a PC and the Internet
Specific prerequisites for this course:
A bachelor degree in sciences is required.

2. Learning outcomes

To impart knowledge and understanding of analysis of signals and systems when considered in the time and frequency domains, and to enable the student to formally analyse systems through the use of spectral analysis and correlations. The student will also be able to take account of the effects of sampling in the time and frequency domain and understand how these affect the practical analysis procedures. The students will be able to select the appropriate infinite or finite impulse response digital filter and undertake the design of the filter coefficients. The student should gain a familiarity with the derivation of the fast Fourier transform (FFT) algorithm and with its computational advantages. An appreciation of simple sample rate changes and their effect on the filter design process would also be expected.

A student should be able to:
  1. Explain the relationships between and be able to manipulate time domain and frequency domain representations of signals.
  2. Apply correlation techniques to an analytic or numerical problem, and relate the outcome to the properties of the signal source(s).
  3. recall how the discrete Fourier transform arises and recognise the effect of resolution and windowing functions upon the discrete Fourier transform;
  4. derive the structure of the fast Fourier transform from the equation of the discrete Fourier transform
  5. analyse the effects of downsampling and upsampling on a signal and recognise the importance of decimation and interpolation filtering.
