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.
Noise Sources • Naturally occurring noise – thermal radiation generated through the random thermal motion of electrons in a conduction medium. Thermal noise is system inherent. – extraterrestrial noise the noise sources are both thermal and none-thermal emission from the Sun,
Analysis of Noise in Image Sensors. Temporal noise in an image sensors is due to: Shot noise of photodetector photo and dark currents Thermal/shot noise of transistors used for readout and ampli cation 1/f noise of photodetector and transistors Substrate and supply voltage noise Quantization noise.
4.1 Definition of Noise. desired signal in a system. Stated another way, any interfering signal, which is usually noticed as random fluctuations in voltage or current tending to obscure and mask the desir. d signals is known as noise. These unwanted signals arise from a variety of sources and can be classified as man.
Noise Principles in Optical Fiber Communication. Abstract: This chapter contains sections titled: Introduction Receiver Thermal Noise Dark Shot Noise Signal Shot Noise Multiplication Shot Noise Optical Amplification and Beat Noises Optical Noise and Coherence Relative Intensity Noise Mode Partition Noise Modal Noise Reflection Noise ...
