- 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 <[email protected]>

Med följande applet kan du titta på ringmodulatorns båda kopplingstillstånd var för sig. Dioderna antas sakna tröskelspänning och transformatorerna antas överföra 1:1. Dessutom antas en fyrkantsformad spänning för $U_2$, vilket ger hård omkoppling. Ett utgångsfilter måste sedan filtrera bort de höga frekvenser som uppstår.<br><br>

Multiplikationen av $U_1$ och $U_2$ fungerar!
