ELT-10016 Signals and Measurements, 4 cr
Additional information
The course gives an introduction to signals and related concepts. The main focus is on electrical signals which are essential, e.g., in electrical engineering, electronics, communications engineering, and information technology. The introduction to signals happens by doing practical measurements. At the same time we learn how to use typical measurement equipment and we get to know the basic electronic components. The course gives a practical introduction to subjects which are discussed in more detail and in more theoretical manner in later courses.

Completing successfully all the laboratory works gives course grade 1. Better course grades (2-5) can be achieved by taking an exam in addition to the mandatory laboratory works. |
Learning Outcomes
After completing the course, the student 1) knows measurement principles and error sources, 2) knows how to use basic laboratory equipment, a simulation software and a data acquisition device, 3) knows how to measure current and voltage, 4) knows the concept of frequency spectrum and is able to measure and interpret it using a measurement device, 5) knows the signal sampling principle and the sampling theorem.

Instructions for students on how to achieve the learning outcomes
Completing all the mandatory laboratory works requires moderate knowledge of the core content of the course and hence course grade 1 is earned. By participating also to the exam, the student can show deeper knowledge of the course content and therefore course grades 2-5 can be earned.
