Executive Summary
This document is one in a series of technical monographs providing a high-level overview of a given topic. Here, noise figure is discussed.
Scope
Noise figure is an important parameter for amplifiers and similar devices, and passive circuits and components. Noise figure expresses, in decibels, the degradation of input carrier-to-noise ratio to output carrier-to-noise ratio for, say, an individual amplifier or a cascade of amplifiers, when the input noise to the device consists of only thermal noise at a standard noise temperature T0 (usually 290 K). Lower noise figure values are an indicator of better performance.
Benefits
The material in this document can be used as part of technical training programs, a tutorial for individuals seeking a high-level understanding of noise figure, and/or a refresher for those who may have forgotten some of the fundamentals of the topic.
Intended Audience
The intended audience for this document includes technical personnel from installers to engineers. The material is also suitable for those new to the cable industry.
