    7. Objectives, learning outcomes and obtained knowledge

    The main objective of the course is to familiarise students with the physical fundamentals of electricity, which is essential in their profession and in everyday life, and its practical application in computing devices. An important aim of the course is to provide insight into the operation, circuitry and design of devices that execute programs.
    Students are introduced to the conceptual framework of basic electrical quantities, and are introduced to the subject of electrical networks. Then, by describing sinusoidal and periodic signals and explaining transient behaviour, they move on to a more theoretical level where active electronic components can be studied in conceptual and simple working models. They are also introduced to the hardware fundamentals of digital technology by introducing the topic of integrated circuits. The fundamentals of electronic design and assembly techniques will also be introduced to develop a hardware approach. As an introductory, and at the same time systematic, topic, the perception of physical reality by sensors is covered.


    It is important that the curriculum concludes with an example of a working circuit, so that the student can relate theory to practice.


    During the laboratory exercises, students will learn the basics of laboratory work (equipment, basic requirements, report writing), the use of measuring instruments, simple signals, passive and active components. And by studying pulse parameters and circuit transients, they can link theory to practice and physical reality.

    9. Method of instruction Lectures and lab exercises.
    10. Assessment During term time:
    There will be three concentrated laboratory sessions, each lasting 4*45 min, in which participation is compulsory.

    At the beginning of the laboratory sessions, a short (about 15 minutes) level assessment is written, which can be prepared from pre-issued measurement aids.

    There will also be a summative assessment (final exam) during the semester.

    A signature is obtained by the student who has fulfilled all the following conditions:
    - Successfully participated in all three laboratory exercises, i.e.
    - successfully completed the entry level assessment, performed and documented the measurement tasks to a satisfactory standard.
    At least a satisfactory level in the final exam.
    During the exam period The course ends with a written exam, which determines the final grade.

    During the exam period:
    The course ends with a written exam, which determines the final grade.

    11. Recaps

    According to the Code of Studies, there is a one-off possibility to supplement or improve the summative assessment. During the make-up period, an additional make-up exam will be held.

    One laboratory session can be made up during the semester, typically at the end of the semester during the make-up period.

    12. Consultations During the semester, on demand.

    IMSc program Students participating in the IMSc programme, which is part of the laboratory exercises for the subject, are placed in separate groups. For the students participating in the programme, some laboratory exercises will be supervised by the most experienced colleague in the field (who is/has been doing research in the field), who will introduce the students to the current research topics and recent results in the field, in addition to the basic laboratory material.
    IMSc score IMSc scoring is based on the extra tasks given in the 1 summative assessment for the subject.

    The percentage of extra tasks scored in the summative assessment is 25%.

    Plus IMSc points can be earned above a 75% pass mark in the summative assessments.

    The maximum IMSc score in the subject is 15.

    IMSc credits are also available to students who do not participate in the programme.
