BJT and JFET Frequency Response   Decibels Power and audio levels are related on a log basis. That is an increase of power level, say from 4 to 16 does not increase the audio level by a factor of 16/4=4. rather it will increase the audio level by a factor 0f 2, as obtained by (4) 2 =16. To increase the audio level by a factor 3, the power level should be increased from 4 to (4) 3   = 64.                    Bell is defined by the following equation-   Bell is a too large unit, so decibel is used, as defined by,   dBm   P1 is accepted as 1mW, then
