- Sections and slides rewritten in Swedish; German law and institutions replaced by Swedish/CEPT/ITU equivalents (PTS, SSA, PTSFS 2025:1, SSMFS 2008:18), unverified statements marked "% TODO VERIFY" - New toc: INSTEG, HAREC, UPPGRADERING; section idents are Swedish (see ident-map.tsv) - Exam-question tags, BNetzA question pool, solutions and the German SWL course removed - Static pages, snippets, applets, READMEs and image alt-texts translated - TikZ labels translated; SVG drawings regenerated (drawing 689 still fails to build upstream: it references a missing photo) - Changed from the original: not endorsed by DARC e.V., SSA or PTS Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

### Avbildning av frekvensområdet vid I/Q-metoden
|
|
|
|
* I/Q-dataströmmen avbildar frekvensområdet kring en mittfrekvens
|
|
* Exempel:
|
|
* $\qty{435}{\mega\hertz}$-bärvåg
|
|
* Samplingshastighet på $\num{10}$ miljoner samplingar/s $\rightarrow$ bandbredd = $\qty{10}{\mega\hertz}$ ($\pm\qty{5}{\mega\hertz}$ kring mittfrekvensen)
|
|
* Täckt område: ca $\qty{430}{\mega\hertz}$ till $\qty{440}{\mega\hertz}$
|
|

### Bandbreddens beroende av samplingshastigheten
|
|
|
|
* Den täckta bandbredden i $\unit{\hertz}$ motsvarar samplingshastigheten i samplingar per sekund
