百科释义
The signal level in an audio signal chain, on an audio recording, or in a radio frequency communication is the measure of the level of the signal emitted or received. Signal level is often related to signal-to-noise ratio (SNR) in the fields of communication theory, science, and engineering, which measures the ratio between an arbitrary signal level and noise.
