| Name: | Discrete-Time Signals |
| ID: | m0009 |
| Language: | English (en) |
| Summary: | Signals can be represented by discrete quantities instead of as a function of a continuous variable. These discrete time signals do not necessarily have to take real number values. Many properties of continuous valued signals transfer almost directly to the discrete domain. |
