Signal-to-noise ratio in spectroscopy

The signal-to-noise ratio is a measure of the quality of a peak that is proportional to the square root of the number of scans used to measure a spectrum.

What is meant by signal-to-noise ratio?

What is the signal-to-noise ratio? In analog and digital communications, a signal-to-noise ratio, often written S/N or SNR, is a measure of the strength of the desired signal relative to background noise (undesired signal).

What is a good signal-to-noise ratio?

Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications. Learn more about Signal-to-Noise Ratio.

What is signal-to-noise ratio in RF?

Signal-to-noise ratio (SNR) is a measure of the level of a desired signal against the level of background noise, measured in decibels (dB).
