In telecommunications, the term received noise power has the following meanings:
1. The calculated or measured noise power, within the bandwidth being used, at the receive end of a circuit, channel, link, or system.
2. Received noise power The absolute power of the noise measured or calculated at a receive point.
Note: The related bandwidth and the noise weighting must also be specified.
3. The value of noise power, from all sources, measured at the line terminals of telephone set's receiver.
Note: Either flat weighting or some other specific amplitude-frequency characteristic or noise weighting characteristic must be associated with the measurement.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
