SuperminarenandClaude Sonnet 5.5 f7fa8cfbc1 Swedish adaptation: Instegscertifikat and HAREC content

- 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

Raw Blame History

Bruset som hörs beror på mottagarens bandbredd
Brusets effekt kan beräknas ur bandbredderna
T.ex. vid användning av olika filter

$\Delta P_R = \qty{10 \cdot \log_{10}{\left(\frac{B_1}{B_2}\right)}}{\dB}$

Exempel

given: B_1 = \qty{2,5}{\kilo\hertz}
given: B_2 = \qty{0,5}{\kilo\hertz}

$\begin{split}\Delta P_R &= \qty{10 \cdot \log_{10}{\left(\frac{B_1}{B_2}\right)}}{\dB}\\ &= \qty{10 \cdot \log_{10}{\left(\frac{\qty{2,5}{\kilo\hertz}}{\qty{0,5}{\kilo\hertz}}\right)}}{\dB}\\ &\approx \qty{7}{\dB}\end{split}$
