When Noise is the Signal [Measurement Methodology]

Anyone who performs a delicate measurement struggles with noise. It can come from the system itself, or be caused by the environment, for example due to electromagnetic interference. There are situations in which noise is the signal of interest and deserves to be quantified. For example, a sensitive amplifier can be characterized by its noise figure, and a device by its electromagnetic compatibility properties.

Abstract

Anyone who performs a delicate measurement struggles with noise. It can come from the system itself, or be caused by the environment, for example due to electromagnetic interference. There are situations in which noise is the signal of interest and deserves to be quantified. For example, a sensitive amplifier can be characterized by its noise figure, and a device by its electromagnetic compatibility properties.
