Carrier-to-Noise Ratio or CNR. The ratio of carrier signal level to noise level in decibel (dB).

Carrier to Noise Ratio. Ratio of received carrier power and noise power in a given bandwidth, expressed in dB. Directly related to G/T and S/N. In a video signal the higher the C/N, the better the received picture.

This is the carrier-to-noise-ratio, which is the ratio of the received carrier power to the noise power in a given bandwidth; it is expressed in decibels (dB), which is a logarithmic scale.

See Carrier to Noise Ratio.

Refers to the ratio of the satellite carrier (or signal) to noise level in a given channel. Usually measured in dB at the LNA output.

The carrier to noise ratio is a quality idication for satellite reception. Commonly you want this ratio to be as high as possible. This means that we want a very high carrier signal and a very low noise. For digital reception a C/N of 9dB is needed. For analog satellite reception we need at least 12dB.
