WebMay 25, 2024 · RSL readings are an indicator of how well the radio can “hear” information being transmitted from the far end radio. The numbers are always preceded by a minus (-) sign. An example of an RSL reading would be -35. The closer to zero the reading is, the stronger the signal will be. WebFeb 17, 2024 · A helpful way to think of the two concepts is suppose your final measured signal is a superposition of two functions: f = f s + f n. where f s is your signal, and f n is the noise. The signal to noise ratio would be a measure the relative power of these two signals: S N R = P ( f s) P ( f n) Note that the SNR doesn't tell you anything about the ...
