| Bandwidth |
This is the required bandwidth of the transmitter.
The above example represents "16.0kHz bandwidth".
The decimal point is replaced with "H", "K", "M", or "G".
These define as: |
| H |
= Hertz |
| K |
= Kilohertz |
| M |
= Megahertz |
| G |
= Gigahertz |
| |

| C |
= AM, vestigial sideband |
| D |
= Amplitude and Angle Modulated carrier |
