- The average value of a symmetrical waveform is taken over half a cycle because the positive and negative half cycles are equal.
- The average value of an unsymmetrical waveform is taken over a full cycle because the positive and negative half cycles are not equal.
For example, the average value of a sine wave is 0.637 times the peak value, and this is taken over half a cycle. The average value of a square wave is 0.5 times the peak value, and this is taken over a full cycle.
| Waveform | Average value | Cycle taken for averaging |
| Symmetrical | Half the peak value | Half cycle |
| Unsymmetrical | Varies | Full cycle |
