ABSTRACT: With the ever increasing demand for higher communication data rates signal integrity is playing a larger role in the design of modern electronic devices. For years engineers and designers have been trying to eliminate noise in circuits for high speed digital, satellite communications, RF amplifiers and now 5G mm-wave devices. Learn about AWGN, how it is generated, how it is controlled and packaged to help test and validate circuit designs with real world noise. Noise sources can be used in a variety of all communications from wired to wireless to simplify, reduce testing time and design costs.
