Db to power factor
WebPower gain, in decibels (dB), is defined as follows: where is the power applied to the input, is the power from the output. A similar calculation can be done using a natural logarithm instead of a decimal logarithm, resulting in nepers instead of decibels: Voltage gain [ edit] Web49 rows · here is a dopey page that might be useful - so now when you or someone says 'I need so many dB gain or so many dB loss' you can look at what this means as a factor …
