 ```OK. Since we are on the way to be correct and precise: 1) A decibel is not logarithm OF ratios of power. 2) A decibel is a decibel, in other words a number, independently if ratio of power, or voltages or whatsoever unity one likes to use. A 3 dB, for example, is ten times the logaritm of the ratio of powers and 20 times the logaritm of voltages. 3) Saying "2" I meant a generical S/N that's have infinite solutions beeing the ratio of two signals. A 2 dB expresses infact an S that's 1.6 times the noise power or 1.26 times the noise voltage (or current). 73, Mauri I4JMY > > Correction: > > dBs are logarithms OF ratios of power. > > Jim KH7M List Sponsored by AN Wireless: AN Wireless handles Rohn tower systems, Trylon Titan towers, coax, hardline and more.
