SNR – Signal-to-Noise Ratio
From the 2018 TAPR Digital Communications Conference, we learn about a true measurement of signal to noise ratio on some of the most popular HF Digital modes.
Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.
