can anybody immediately reply me the answer for noise bandwidth
 

Re: communication

White noise bandwidth is infinite. Flicker noise is 1/f.

Re: communication

Since any communication system has a front end filter. The noise bandwidth of interest is the bandwidth of this filter.
 

communication

in communication cources:
white noise is supposed to be unlimited but in practice it damp affter 500GHz
 

Re: communication

NOISE BANDWIDTH (NBW)
More accurately: equivalent noise bandwidth. Describes the equivalent bandwidth of a filter for broadband (white) noise and is the bandwidth of a rectangular characteristic filter having the same power transfer function as the selection filter (same area under the curve). The relationship between NBW and the resolution bandwidth (RBW) of a Gaussian filter is approximately:

NBW = 1.2 x RBW
