I know it and you know it.
So it seems only Erik who not understand, that oscillations on a certain position and real movements are fully different things ! And both solutions (hardware and software) are fully able to see the difference. And thus only the real movement determine the needed sampling frequency. And thus it plays absolutely no role, if oscillations on a certain position are in the µHz, mHz, Hz, kHz, MHz, GHz or THz range. I hope that all others except Erik understand it now. Peter P.S.: Its the evolution, that more and more hardware will be replaced by software, since exact the same equations can be wired in hardware or programmed in software. But hardware cost something and software cost nothing. |

| Dont do this. | 01/01/70 00:00 | |
| Signals are not connected directly | 01/01/70 00:00 | |
| Is assembly ok? | 01/01/70 00:00 | |
| For Mehdi | 01/01/70 00:00 | |
| its easy in software | 01/01/70 00:00 | |
| but | 01/01/70 00:00 | |
| same resolution | 01/01/70 00:00 | |
| But...what if ? | 01/01/70 00:00 | |
| So what is the solution? | 01/01/70 00:00 | |
| absolutely no problem | 01/01/70 00:00 | |
| Thank you | 01/01/70 00:00 | |

| Re frequency | 01/01/70 00:00 | |
| So what frequency do we sample at? | 01/01/70 00:00 | |
| I try to explain Peter's idea again | 01/01/70 00:00 | |
| We know it ! | 01/01/70 00:00 | |
| Nothing ??? | 01/01/70 00:00 | |
| it takes time | 01/01/70 00:00 | |
| Code doesn't function | 01/01/70 00:00 | |
| reverse direction ! | 01/01/70 00:00 | |
| This is not a problem | 01/01/70 00:00 | |
| incorrect operation? | 01/01/70 00:00 | |
| right connection ? | 01/01/70 00:00 | |
| I dunno | 01/01/70 00:00 | |
| Now... | 01/01/70 00:00 | |
| check the sample condition ! | 01/01/70 00:00 | |
| clarify | 01/01/70 00:00 | |

| @Peter | 01/01/70 00:00 | |
| Grey code | 01/01/70 00:00 | |
| Grey code more | 01/01/70 00:00 | |
| Grey INCREMENTAL ? | 01/01/70 00:00 | |
| I guess 98 | 01/01/70 00:00 | |
| Gray code | 01/01/70 00:00 | |
| Not a gray code | 01/01/70 00:00 | |
| Grey | 01/01/70 00:00 | |
| Yes of course its Grey code | 01/01/70 00:00 | |
| Absolute Vs Incremental | 01/01/70 00:00 | |
| So now... | 01/01/70 00:00 | |
| Yes it can but only... | 01/01/70 00:00 | |
| Peter is right! | 01/01/70 00:00 | |
