Noise
1010606NoiseIn this chapter, we introduce a number of rules related to the influence of noise in the performance of optical communication systems. In this discussion, we must make a distinction between the definition of signal-to-noise ratio (SNR) as commonly used is the electrical engineering context and the analogous definition for optical systems.In electrical circuits, especially ones that deal with communications (as opposed to conveying power), the designer must evaluate the system to know if the signals are going to be detectable. The most common way to do this is to estimate the signal level a…
