Sigh. Another ineducable newsgroup participant.
The formula for calculating power decibels is:
Po
G = 10 log10 ----
Pi
Where
G = Gain in dB
Po = Power output from the device
Pi = Power input to the device
The formula for calculating voltage decibels is:
Vo
G = 20 log10 ----
Vi
Where
G = Gain in dB
Vo = Voltage output from the device
Vi = Voltage input to the device
Or. if you don't believe me, you can read this tutorial:

You can join Aylward in my killfile. Assuming that he still posts to
sci.electronics.design, the two of you can have your own little flame
war without bothering me with the personal attacks that you think are
an acceptable alternative to having a civil discussion on the topic
at hand. Maybe later in life, after you have learned to read, write,
spell, and count, you will have more success. True, these are rudimentary
skills that many of us "normal" people take for granted that everyone
has an easy time of mastering. But we sometimes forget that there are
"challenged" persons in this world who find these things to be difficult.
If I had known that this was true in your case then I would have never
have exposed myself to what you wrote. It just wouldn't have been
"right." Sort of like parking in a handicap space. I wish you the
best of luck in the emotional, and social struggles that seem to be
placing such a demand on you.
