6.5 Analyzing and calculating noise bandwidth in ADC systems – multi-stage filters


2020年 9月 29日

In this module, we will discuss what effective noise bandwidth is, where it comes from in your system, and how to calculate and simulate the combined frequency response and noise density of multi-stage filters. In a subsequent presentation on effective noise bandwidth, we will analyze a delta-sigma ADC’s digital filter frequency response, and its combined affect with a first-order lowpass filter, to better understand how to calculate total system noise.  The goal for these effective noise bandwidth Precision Labs modules will be to apply the knowledge from these examples to help determine the total noise in your next signal chain design.
