SNR Measurement Techniques

Signal-to-Noise Ratio (SNR) is a measure of the quality of a signal compared to the background noise. It indicates how much desired information is present versus how much unwanted interference exists. Common techniques for measuring SNR include: 1. **Direct Measurement:** Using audio or signal analysis tools to compare the levels of the signal and noise. 2. **Spectrum Analysis:** Visualizing the signal and noise in a frequency domain to quantify their levels. 3. **Statistical Methods:** Evaluating the signal power against the noise power through calculations. High SNR means better quality, while low SNR indicates more noise affecting the signal.
