Abstract

Data acquisition systems are used in many industries, from automotive test to aerospace and defense. The front-end of a data acquisition system presents key challenges as the system must have sufficient bandwidth to capture the input signal without introducing frequency response distortion, phase shift, or attenuation that can compromise the signal's integrity. This application note discusses the design of an anti-aliasing filter for a 100kHz data acquisition signal chain.
