| 9.2 Sinusoids (2) |
|
|
| A periodic function is one that satisfies v(t)
= v(t + nT), for |
|
| all t and for all
integers n. |
|
|
|
|
|
|
|
| • | Only two
sinusoidal values with the same
frequency can be |
||||
| compared by
their amplitude and phase difference. |
|||||
| • | If phase difference is zero, they are in phase; if phase |
||||
| difference is not zero, they are out of phase. |
