There are various dBx measures of real signal characteristics. The
most common ones that I know of are dBm (dB over 1mW), dBV (dB over
1V, presumably ignoring impedance and therefore really just a
fancy-pants amplitude measure) and dBc (dB under carrier, very
important stuff to measure phase noise in an oscillator or transmitter).

======================================
RF power limitations (power into antenna) for the UK amateur radio
licences are expressed in dBW 26 dBW equals 400 Watts
15 dBW equals 32 Watts etc .

Why not just say Watts or milliwatts and be done with it?
Why drag dB into it?

BTW dB means deci-bell, why not use a WHOLE BELL.
(and the brass figligee with bronze oak-leaf palm to anybody
who can guess who this unit of measure was named after!)
