### Course description and aims

This course covers fundamental topics on complex analysis, Laplace transform, and Fourier analysis, which are essential in the field of systems and control engineering. Specifically, it is important to be aware of the connection between time domain and frequency domain characterizations.
In this course, we focus on linear systems and go over calculus of complex functions, residue theorem, deriving solutions of differential equations with Laplace transform, periodic functions and Fourier series, aperiodic functions and Fourier transform, and convolution theorems.

### Student learning outcomes

By the end of this course, students will be able to:
1) Understand fundamental facts in complex analysis
2) Compute complex integral for real-valued functions
3) Explain characteristics on signal and systems and characterize connections between time domain and frequency domain
4) Acquire fundamentals of Laplace transform and apply it to solve linear dynamical systems
5) Expand periodic functions in Fourier series and characterize aperiodic functions using Fourier transform

### Keywords

Complex variables, Complex functions, Cauchy-Riemann equations, Complex integral, Cauchy's integral formula, Residue theorem, Conformal mapping, Laplace transform, Partial fraction expansion, Final value theorem, Fourier series, Fourier integral, Fourier transform

### Competencies that will be developed

 ✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

### Class flow

At the beginning of each class, some of the important points learned in the last class are reviewed. Then the main topics for the day is covered in detail. Students are advised to solve exercise problems at home.
