Signals and Systems

FEKT-BPC-SISAcad. year: 2023/2024

This module provides an introduction to the linear time-invariant continuous- and discrete-time signal and systems. Students are introduced with the various methods of description and analysis of the continuous- and discrete-time signals and systems: time domain, frequency domain, spectrum, Fourier series, sampling, transforms (Laplace, Fourier, Z) and differential equations. These methods are used to analyse signal and system properties and to determine basic characteristic: linearity, time-invariance, causality, stability, power, etc.

Aims

The purpose of this module is to provide students with the theory of the linear signals and systems with the continuous- and discrete- time and with the fundamental principles of their analysis.
By the end of the module, the student will be able to:
Describe continuous and discrete time signal in time and frequency domain.
Perform continuous and discrete time signal transform using the Fourier series, the Fourier transform, the Laplace transform and the Z-transform.
Discuss practical interpretations of these transforms and their properties.
Describe fundamental properties of LTI continuous-time systems.
Describe fundamental properties of LTI discrete-time systems.
Use the different methods to describe LTI systems.
Determine system response of an LTI system to standard and general signals.
Determine from the description of the LTI system its characteristics such as linearity, time-invariance, causality and stability.
