Signal-to-Noise Ratio
Signal-to-Noise Ratio (SNR) measures the desired signal's strength compared to background noise. Imagine trying to listen to your favorite music at a café. The music is the signal, while the chatter and clinking dishes are the noise. A high SNR means you can hear the music clearly despite the distractions, indicating good quality. Conversely, a low SNR means the noise overwhelms the music, making it hard to enjoy. In various fields like telecommunications and audio, a higher SNR typically means better clarity and quality in what we are trying to perceive or communicate.
