White Paper Overview

When designing a measurement signal chain, it is important to work through a noise analysis to determine if the signal chain solution will have low enough noise so that the smallest signal of interest can easily be extracted. A thorough noise analysis can save time and money during the production process. This article will outline the main steps necessary to carry out a signal chain noise analysis.

This article by Analog Devices presents the steps needed to carry out a theoretical analysis on the noise performance for a high speed wide bandwidth signal chain.
