Received noise power


In telecommunications, received noise power is a measure of noise in a receiver. For example, the received noise power might be:
  1. The calculated or measured noise power, within the bandwidth being used, at the receive end of a circuit, channel, link, or system.
  2. The absolute power of the noise measured or calculated at a receive point. 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 a telephone set's receiver.' Either flat weighting or some other specific amplitude-frequency characteristic or noise weighting characteristic must be associated with the measurement.
