Hi All
I am abit stuck on converting a number in decibels (Db) to signal/noise
ratio.
I know the equation for converting into DB: -
SN (Db) = 10 Log [Signal Power / Noise Power]
The way which I have managed to conver the Decibel to S/N is using the
following formula: -
Inverse Log [XXXX db / 10]
So using the above formula, 30 Db will work out to be 1000 s/n which is
correct.
The problem is, explaining how I got this formula. Any ideas or better ways
of working this out would be appreciated.
Regards
Karl
