Signal-to-Noise Ratio (SNR)
Signal-to-noise ratio is the difference between the relative strengths of the noise floor power level and the intended signal power level.

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 )

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
