Bandwidth and frequency don't seem related at a casual glance - one is a single point on the frequency line, the other is a span on the frequency line. I'm just trying to resolve that confusion. | |
| Mar 15, 2022 at 5:43 | comment | added | TimWescott | So you're proposing a means of transmission that has a bandwidth more than 6MHz because you want a bandwidth less than 6MHz? | |

| Mar 14, 2022 at 23:05 | comment | added | Chris Akridge | @MarcusMüller I'd hazard a guess at ~6MHz, but I didn't want to assume that, since I don't know if a conversion from bits-per-second to cycles-per-second is valid (kinda like how liters and grams aren't compatible). | |

| Mar 14, 2022 at 16:33 | comment | added | Marcus Müller | So, what do you think is the bandwidth of something that changes 6.46 million times a second? | |
