| Fill out the gray box and click at the respective calculation bar under it. Don't forget to enter the minus sign with the distortion attenuation in decibels. |
| The distortion factor is always smaller than 1 or less than 100 %, therefore the distortion attenuation must be a negative dB value. Distortion attenuation: Distortion factor THD: |

in dB
where V2 to Vx are the amplitudes of harmonics to the fundamental amplitude V1.

| Enter simply the value to the left or the right side, and use the TAB key or click the mouse to an empty space on the page to get to the solution. The calculator works in both directions of the ↔ sign. The distortion attenuation in dB must begin with a minus sign. |
| Don't forget the minus sign, when entering the distortion attenuation in decibels. |
