Signal Noise Ratio

Signal Noise Ratio

Signal Noise Ratio

The signal-to-noise ratio (SNR) is a crucial metric that measures  the amount of useful information vs. false or irrelevant background noise, frequently measured in decibels (dB). Engineers aim to maximize SNR to enhance system performance by minimizing noise interference.
