FUNDAMENTALS OF ELECTRICAL ENGINEERING + INTRODUCTION TO ELECTRONICS (UNIT 2)
Learning outcomes of the course unit
The aim of this module is to provide students with basic knowledge of sensing devices and transducers, automatic control techniques, and signal processing in the field of mechatronic applications.
The students are expected to be familiar with the notions of mathematics, physics, electrical and electronic circuits taught in the 1st level degree in Mechanical Engineering.
