Course content

Fundamentals of complex algebra. The Laplace transform, applied to signals and linear systems. Convergence, inverse transform, properties.Impulse response and convolution. Transfer functions. Block diagrams and manipulation rules. "s" as a differentiation operator.
The Fourier transform, also as a special case of the Laplace transform. Fourier series and -transform of signals and for linear systems, common traits of signals and systems. Impulse and frequency response. Signal spectrum. Bilateral Fourier and Laplace transform. Convergence and existence. Impulse function in the frequency plane.
State space models with vector differential equations and use of linear algebra. Transition matrix, decoupling, similarity transformation. Relation to Laplace: resolvent matrix and transfer matrix.
Systems and signals in discrete time. Sampled systems. The sampling theorem. The zero-order hold and its phase effect. Analysis and synthesis via approximation in continuous time. Z as a time shift operator. Briefly and practically about stochastic signals and noise, analog and discrete filters.

Learning outcome

Knowledge: Basic knowledge about mathematical tools for describing and analysing linear time-continuous signals and dynamic systems described by time responses and differential equations. Basic knowledge about models of systems in the form of n-dimensional differential equations. Knowledge of concepts like vector differential equations, state space model, eigenvalues. Knowledge of concepts like impulse- and step response,poles and zeros, block diagram and feedback.

Basic knowledge about modeling and analysis of continuous dynamical systems with transfer functions and frequency analysis, and representation of signals in the frequency domain. Knowledge about the Laplace- and Fourier transformations, and their connections, applied to signals and systems. Knowledge about the connections between state space models and transfer function models, and the equivalences between signals and linear systems. Knowledge about the most important types of signals and their spectral (frequency domain) representation. Knowledge about stability in linear systems.

Skills: Be able independently to model, and analyse signals' and dynamical systems' properties algebraically, and also numerically with MATLAB. - To find system time responses using the Laplace transform, via tables or residue calculus. - To do elementary analysis of signals and filter design in continuous and discrete time.

General competence: Be able to think about and apply the concepts of systems theory when considering technical and also non-technical systems. Be conscious about how this theory may contribute when cooperating with other disciplines.
