Signal-to-Noise Ratio (SNR)

Signal-to-noise ratio (SNR) measures the clarity of a signal compared to background noise. Imagine you're at a concert: the music is the signal, while the chatter of the crowd is the noise. A higher SNR means the music is much louder than the chatter, making it easier to hear. In communication and technology, a better SNR indicates clearer audio, video, or data transmission, resulting in fewer errors and better quality. Essentially, it quantifies how much the meaningful information stands out against unwanted interference.
