## Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to describe different properties of linear systems, and to explain how they can be modelled in the time domain and in the frequency domain.
• be able to define the Laplace transform and account for its significance in connection with input/output relations and the solution of differential equations, and be able to use  simple transform tables to determine transforms/inverse transforms.
• be able to use matrix theory to analyse quadratic forms and to solve systems of linear differential equations.

Competences and skills
For a passing grade the student must

• be able to demonstrate the ability to identify problems that can be modelled with linear systems, and be able to analyse the corresponding models.
• be able to demonstrate the abilty to use the introduced concepts in connection with  problem solving.
• with proper terminology, suitable notation, and with clear logic be able to explain the solution to a problem in a well structured manner.

## Contents

Linear systems: Mathematical models of linear, time invariant systems. Transfer function. Step response and impulse response. The frequency function.

The Laplace transform: Step and impulse functions. Computational rules for the two-sided Laplace transform. Inverse transforms, in particular of rational functions. Use of transform tables. Convolution.

Matrix algebra: Eigenvalues and eigenvectors. Diagonalization, in particular of symmetric matrices. Quadratic forms, diagonalization and classification. Systems of differential equations: solution by diagonalization, solution using exponential matrix.
