Project Description

Course Overview

This short online course introduces the concept of noise in RF and microwave systems and how it is measured. It begins by defining a basic noise equation before explaining how noise sources are used to provide a known reference for measuring noise figure. The course concludes with a review of a typical noise figure measurement system and how to use a noise figure meter. A review quiz is included to test knowledge and understanding.
