Noise power

In telecommunication

Telecommunication

Telecommunication is the assisted Transmission of Signal over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, Drum , Semaphore line, flag signals or heliograph....
, the term noise power has the following meanings:

The measured total noise
Noise

In common use, the word noise means unwanted sound or noise pollution. In electronics noise can refer to the electronic signal corresponding to acoustic noise or the electronic signal corresponding to the noise commonly seen as 'Noise ' on a degraded television or video image....
per bandwidth unit at the input
Input

Input is the term denote either an entrance or changes which are inserted into a system and which activate/modify a process. It is an abstract concept, used in the model ing, system design and system exploitation....
or output
Output

Output is the term denote either an exit or changes which exit a system and which activate/modify a process. It is an abstract concept, used in the model ing, system design and system exploitation....
of a device when the signal is not present.
The power
Power (physics)

In physics, power is the rate at which mechanical work is performed or energy is transmitted, or the amount of energy required or expended for a given unit of time....
generated by a random electromagnetic process.
Interfering and unwanted power in an electrical device or system
System

System is a set of interacting or interdependent entities, real or abstract, forming an integrated whole.The concept of an "integrated whole" can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the se...

In the acceptance test

Acceptance test

In engineering and its various fields of engineering, acceptance testing is black-box testing performed on a system prior to its delivery. It is also known as functional testing, black-box testing, ITIL, QA testing, application testing, confidence testing, final testing, validation testing, or factory acceptance testing....
ing of radio

Radio

Radio is the transmission of signals, by modulation of electromagnetic radiation with frequency below those of visible light.Electromagnetic radiation radio propagation by means of oscillating electromagnetic fields that pass through the air and the vacuum of space....
transmitters, the mean power supplied to the antenna transmission line

Transmission line

A transmission line is the material Transmission medium or structure that forms all or part of a Course from one place to another for directing the transmission of energy, such as electromagnetic waves or acoustic waves, as well as electric power transmission....
by a radio transmitter when loaded with noise

Noise

In common use, the word noise means unwanted sound or noise pollution. In electronics noise can refer to the electronic signal corresponding to acoustic noise or the electronic signal corresponding to the noise commonly seen as 'Noise ' on a degraded television or video image....
having a Gaussian amplitude-vs.-frequency

Frequency

Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency.The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency....
