Course objectives
The course focuses on digital processing of one-dimensional signals in physics, monitoring technology as wel as in other areas.
Syllabus
  • 1. Basic concepts. Signal continuous, discrete, digital, fields of application, stages of processing, classification of discrete signal processing methods, advantages and disadvantages of discrete and digital signal processing, signals 1D, 2D and multidimensional.
    2. Fourier series (FS) and Fourier transform (FT) continuous signal. Definitions and properties, FT of basic signals, the effect of sampling, convolution and correlation.
    3. Sampling and reconstruction of signal. Ideal and real sampling signal, sampling theorem and alias, reconstructive filter and interpolants.
    4. The Fourier transform of a discrete signal. DTFT, DFT, their inversion and properties.
    5. Discrete unitary transform. Transformation kernel, unitarity, hermiticity, examples: Hadamard, Walsh, DFT, Haar, fast methods of DFT (FFT).
    6. Deterministic and stochastic signals. Stability and causality, linear time-invariant (LTI) systems.
    7. The transfer function, impulse response of the system, bias (in relation to the transmission bandwidth).
    8. Digital filtering and designof digital filters - FIR, IIR (numerical realization of convolution integral, low-pass filter for noise removal, narrowband filters, nonlinear filters, removing cracks).
    9. Wavelet transform (WT). Time-frequency analysis, continuous, discrete WT (CWT / DWT), Daubechies-type DWT, WT implementation by filter banks.

The course can also be completed outside the examination period.
Teacher's information
Semester exam has oral part only. Knowledge of the nature of discussed methods, supplemented by practical examples, are required. Knowledge of mathematical nature and pictogrammatic approach has precedence over reciting the mathematical formulas (e.g., when discussing the properties of Fourier transform, knowledge of basic transformation pairs and explaination of their properties are required).
The course is also listed under the following terms Summer 2010, Summer 2011, Summer 2012, Summer 2013, Summer 2014, Winter 2014, Winter 2016, Winter 2017.
