Circuits & Electronics
Students are able to characterise and analyse electric circuits regarding 1st and 2nd order systems in the frequency (filters) domain with the aid of various signal descriptions, complex number theory and differential equations; furthermore, students are able to characterise and analyse electronic implementations of these systems.
Finally, students are able to analyse, design and synthesis circuits containing active elements (i.e. Bipolar Junction Transistors used as switch and as (audio amplifier), Opamps used in various circuit configurations).
Modelling and Control
Students are able to model and analyse dynamical systems from an energybased perspective with the aid of Laplace transformation and block diagrams; characterise, analyse and implement feedback control (PID) in the digital domain.
Systems and Signals
Students are able to understand the mathematical descriptions of simple real and complex signals and of simple LTI systems, in both time and frequency domains, with advantages and disadvantages; learn the mathematical techniques that allow switching between the two representations.
Hackathon
The students at the end of the Hackathon should be able to: integrate knowledge on sensors, electronics and control; creatively construct a demonstrator with limited resources; apply (feedback) control in practice; select the right sensors and actuators for the job and use wellchosen electronics for interfacing sensors and actuators.
Manual enrollment via Osiris is only for Creative Technology students.
Enrolment is open to students from other bachelor programmes who are allowed to follow the module as a minor/exchange programme. Note that the Smart Tech module and its courses are not open for students from all study directions! Check the entry rules at the minor office for the most recent entry requirements. If you want to enroll, please contact K. Zalewska (k.zalewskakurek@utwente.nl).



The foundation of Smart Technology is Circuits and Electronics in which passive and active electronic components and the analysis and operation of basic electric circuits (transients, filtering, amplification, etc.) will be laid down. To be more precise, the following topics will be treated: signal descriptions in time and frequency domain (e.g. average values, RMS values, Fourier series); the passive components R, L and C and their current, voltage and power relations; step responses in 1st and 2nd order passive circuits; complex impedances; 1st and 2nd order passive filters; electronics such as the active (semiconductor) components diodes, LEDs, bipolar junction transistors (both as a switch and as an amplifier) and Opamps.
In the course Modelling & Control, students will learn basic techniques to control/move/ interact with something physical (a mechanical system) with an electrical system. This will provide you with the tools to add an extra dimension to your creations  interaction with the physical world. The course has both a strong theoretical part as a significant practical part in the form of 3 elaborate lab sessions in which you will apply the theory. In this course, you will learn the basics of modelbased control engineering. The first half of the course will be on modeling and the second half on control.
Systems and Signals provides the mathematical background necessary to support the Smart Technology related courses. The first half of the course focuses on the time domain representation of signals and systems; it covers trigonometric functions, complex numbers and simple secondorder differential equations. The concept of Fourier series is also introduced, in preparation for the second half of the course, that focuses on the frequency domain representation. The main topic of the second half is the Laplace transform, its properties and its application to the study of simple interconnections of systems and their behaviors. The topics are coordinated with the other courses in order to keep a close relationship between the mathematical foundation and the application within the ST context.
The Hackathon is a creative group project in a pressurecooker setting aimed at integrating and grounding the content from the modules core courses in one design. A (technical) challenge has to be solved and a demonstrator has to be built with a limited set of materials in a limited amount of time, requiring the knowledge gained throughout the module on Sensors, Electronics and Control.
Prerequisite Knowledge

Neil Storey, "Electronics, A Systems Approach", 6th edition, Pearson Education Limited, 2017. Chapters of interest are:
Chapter 1 (back to basics); Chapter 3.1  3.7 (DC network theory); Chapter 4.1  4.4, 4.7  4.8 (capacitors); Chapter 5.1, 5.4  5.5, 5.8 5.9 (inductors); Chapter 6.1  6.2 (iv relationships in R, C and L for sinusoidal functions); Chapter 8.1 – 8.4, 8.10 (filters); Chapter 9.1 – 9.4 (1st order systems); Chapter 14.1 – 14.4 (basic concepts of amplification)
Modeling & Control: The course Modelling & Control requires the following prior knowledge:
 Mathematical skills: see the prerequisites for the Systems & Signals course, especially proper understanding of and ability to apply the concepts of differentiating and integrating.
 Intro to Physical Systems in module 3. Key points from that course are: System, system boundaries, physical domains; Energy and power; Energy storage, Energy dissipation and system states; Basic modelling skills in electrical and mechanical domain (sources, Ctype elements, Itype elements, Rtype elements); structures in Electrical domain (Kirchhoff's law) and mechanical domain ('d Lambert law) for analysis and modeling of networks in electrical and mechanical domains; Analogies between electrical, mechanical and hydraulic domain. This prior knowledge can be acquired via the study of chapters 14 and 7 of the book: “Dynamical Systems for Creative Technology” by Job van Amerongen, 3rd edition, Enschede, 2012.
Note that this course has strong ties with other courses in the modules such as Systems & Signals and Circuits & Electronics. A good understanding of fundamentals taught in those courses is relevant. Examples for Circuits & Electronics are: step responses in 2nd order electrical circuits and 2nd order filters (incl. their analysis in the frequency domain using Bode plots), analysis and/or synthesis of basic amplifier or active filter configurations using Opamps. Examples for Systems & Signals are: solving 1st and 2nd order, linear differential equations, complex number theory, Laplace and inverse Laplace transformation, analysis in the frequency domain (either via Bode plots (jw  domain) or via the sdomain).
