In forum communications, the forum signal-to-noise ratio, often written FS/N or FSNR, is a measure of signal (post quality) relative to background noise (work). The ratio is usually measured in decihillbillies. (dB). If the incoming signal strength in microposts is Vs, and the noise level, also in microposts, is Vn, then the forum signal-to-noise ratio, FS/N or FSN, in decihillbillies is given by the formula FS/N = 20 log10(Vs/Vn)
Ideally, Vs is greater than Vn, so S/N is positive. As an example, suppose that Vs = 10.0 microposts and Vn = 1.00 micropost Then S/N = 20 log10(10.0) = 20.0 dB which results in the signal being clearly readable. If the signal is much weaker but still above the noise -- say 20 microposts in as many days—then FS/N = 20 log10(1.30) = 2.28 dB which is a marginal situation where there might be some reduction in response under these conditions.
If Vs is less than Vn, then FS/N is negative. In this type of situation, reliable communication is generally not possible unless steps are taken to increase the post quality level and/or decrease the noise level at the destination (receiver).
Forum participants always strive to maximize the FS/N ratio, although negative posters create a less than magnetic effort by bombarding the crowd with demanding posts. This repetitive noise is balanced by ignoring the data requests, thereby improving the content and throughput.
