What is Attenuation? - Definition from WhatIs.com

WebThe noise addition of optical amplification can easily be extended to optical attenuation, accordingly with the fluctuation dissipation theorem. In the same way as amplification, as expressed by Eq. 3.72 , it can be shown that the spectral density of added quantum noise for a device with an attenuation coefficient A is S A = ( 1 − A ) h ν / 2 . WebABSTRACT The presence of noise in towed marine seismic data is a long-standing problem. The various types of noise present in marine seismic records are never truly random. Instead, seismic noise is more complex and often challenging to attenuate in seismic data processing.
