The ratio of the power or volume (amplitude) of a signal to the amount of disturbance (the noise) mixed in with it. Measured in decibels, signal-to-noise ratio (SNR, S/N) measures the clarity of ...

Frequency range is the range of output frequencies that a noise meter can identify. The noise figure (NF) is the ratio (in dB) of the signal-to-noise ratio at the input of the component and the signal ...

Noise figure meters measure the noise contribution of an amplifier relative to a noise-free amplifier at a reference temperature. For most Ku-band amplifiers, values are expressed in decibels (dB).

The authors measured the signal-to-noise ratio and how the material performs with different levels of noise. They also tested the impact of the material thickness on performance measures.

The ratio of interference in a circuit or line to the noise. A signal-to-noise ratio (SNR) deals with noise that comes from the inherent qualities of the electronic components or the atmosphere ...
