Signal-to-Noise Ratio (SNR)
Total noise power is a combination of thermal noise and any noise added by the system. Higher signal-to-noise values are better since there is less of a probability that signal corruption and data errors will occur.
| SNRrx = Prx - 10 log ( k Ta B ) { dB } | |
| where: | SNRrx = signal-to-noise ratio at detector ( dB ) |
| k = Boltzmann's constant = 1.380 · 10-23 ( J/K ) | |
| Ta = ambient temperature ( K ) | |
| B = receiver bandwidth at detector ( Hz ) | |
