Question

Explain and prove the ff questions:

1. The logarithm of a number gives the power to which the base must be brought to

obtain the same number. If the base is 10, it is referred to as the common logarithm; if the base is e = 2.71828c, it is called the natural logarithm.

2. Because the decibel rating of any piece of equipment is a comparison between levels, a

reference level must be selected for each area of application. For audio systems the reference level is generally accepted as 1 mW. When using voltage levels to determine the

gain in dB between two points, any difference in resistance level is generally ignored.
