Introduction to Radio Concepts
In this course the basic concepts of radio principles are introduced starting with an overview of the electromagnetic spectrum, with a primary focus on the area of radio communications. The course will progress and provide some basic radio communication terms and concepts before providing a focus on antennas used within radio communication systems. It will then finish off with an overview of the techniques utilised in modulation, duplexing and multiplexing.
