Which Are Logarithmic And So Cannot Be Manipulated Without Being Converted Back To A Linear Scale.

Log (100) = log (102) = 2 multiply this result by 10 to find the number of decibels. With the scaling menu you can choose between power calculation (10db / decade), or switch over. Other level, or absolute logarithmic scale.

Decibels = 10 × 2 = 20 Db If We Put All These Steps Together Into A Single Equation, We Once Again Have The Definition Of A Decibel.

We will try to express the number 47 as a sum or subtraction of the three important values we saw before: The logarithmic scale can describe very big or very small numbers with shorter notation. 0 db, 3 db or 10 db.

As Can Be Seen Above, The Db Or Log Scale Is A Convenient Way To Represent Large Numbers.

The defining equation for decibels is a = 10*log10(p2/p1) (db) where p1 is the power being measured, and p1 is the reference to which p2 is being compared. Decibel equation—convert voltage or power gain to decibels. An explanation of decibel addition and subtraction is included.
