Electronics (ELE140)

The course provides an introduction to analog and digital electronics. For analog electronics, the dynamic behavior of electrical circuits is examined using transient analysis and frequency response. Understanding and using amplifiers and power transistors in practice is also central. For digital electronics, the course looks at how transistors are used to create more complex logical functions, ultimately resulting in an overarching structure for a microcontroller. Programming a microcontroller using the language C is used to explore this structure in practice.

Circuit Analysis: 1st and 2nd order systems, transient analysis, transfer functions, frequency response, Bode plot, resonance.

Amplifier Theory: feedback, amplification frequency response, linearity. Operational amplifier and instrumentation amplifier.

Power Supply: characteristics, power transistor.

Basic Digital Electronics: number systems, logic circuits, logic functions.

Microcontroller: general architecture, microprocessor, memory, timer, interrupts, C-programming.

The students should:

• be able to find the transient response, transfer function, frequency response, and Bode plot for 1st and 2nd order electrical circuits.
• understand basic specifications and characteristics of an amplifier (e.g., output and input impedance, frequency response, distortion, and linearity).
• be able to to use an operational amplifier or instrumentation amplifier to create amplifier circuits with various properties.
• be able to analyze and size a power transistor.
• be familiar with the basic structure of a microcontroller.
• be able to write simple programs in C.
• be able to develop an overall software structure and code for a simple embedded system based on a specification of desired functions.

Compulsory laboratory exercises:8 Compulsory hand-in assignments: 6 out of 10.

Completion of mandatory lab assignments are to be made at the times and in the groups that are assigned and published. Absence due to illness or for other reasons must be communicated as soon as possible to the laboratory personnel. One cannot expect that provisions for completion of the lab assignments at other times are made unless prior arrangements with the laboratory personnel have been agreed upon.

Failure to complete the assignments on time or not having them approved will result in barring from taking the exam of the course.

Up to 6 hours of lectures and up to 4 hours of laboratory work per week throughout the semester.

Mandatory coursework (such as problem-solving exercises, laboratory assignments, project tasks, and similar) must be approved by the course instructor by the specified deadline.
