The power spectrum of the thermal noise is wide and essentially uniform over the RF spectrum of interest for most communication systems. The shot noise arises from the discrete nature of the current flow in electronic devices (transistors, tubes).
This chapter helps the readers learn how to determine noise power and signal-to-noise ratio at various points in a communication system. It begins with a discussion on the physical sources of noise, which includes quantitative estimates of noise level.
1 Φεβ 2019 · Therefore, this paper aims at ways of reducing the effects of these forms of noise on image and sound files that can be compressed and sent through a communication channel.
11 Δεκ 2021 · The purpose of this chapter is the study of the noise that appears in communication systems. The following concepts are presented: thermal noise, internal noise, the noise of cascaded systems, the noise of an attenuator element and the noise that appear in PCM systems. Download chapter PDF.
