- 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\rightarrowbandbredd =\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
