6.6 Analyzing and calculating noise bandwidth in ADC systems – the digital filter
This module covers digital filter effective noise bandwidth in ADC systems. In this module, we will analyze an ADC’s digital filter frequency response and its combined affect with an anti-aliasing filter. Through a design example, we will identify approximations for the system noise bandwidth to simplify your analysis. You will also learn how a digital filter’s bandwidth often acts as the limiting factor for the entire system.
