Extend DAC resolution for motion control systems
|
2004-07-01 |
| Motion control systems often require digital-to-analogue converters with high resolution but not high accuracy. Because high-accuracy DACs are expensive and consume valuable board space, a good solution is to extend your DAC's resolution in software. This article presents such a technique |
