Suppose we add to the phase of each term an additional phase angle proportional to the frequency of the term. For example:
|
 |
A 6 Component Impulse Train with Modified Phase |
| Amplitude |
Frequency (rad/sec) |
Phase (degrees) |
| 1 |
0 |
90 |
| 2 |

The shape is not changed, but the waveform is delayed in time. |
