+=============== Utkast till titlar ===============
+
+Considerations when automating measurements in a system with <<<high voltage>>> and high frequency components.
+
+Verifying voltage pulses up to 1500 V with high frequency components in time-domain.
+
+Designing an automated verification system for <<<high voltage>>> and high frequency.
+
+
+=============== Utkast till frågor ===============
+
+Alternativ för "fråga 1"
+* What is the best way of acquiring a <<<high voltage>>> signal with high frequency components?
+* How can a <<<high voltage>>> signal with short rise times be measured?
+* -- |  | --, with automatability in focus?
+* -- |  | --, with electrical safety in focus?
+
+Alternativ för "fråga 2"
+* What is the best way to verify the time-domain parameters of the signal?
+* How can the parameters of the signal be verified?
+* Which is the most <<<robust>>> way of analysing the signals time-domain parameters?
+
+Andra utkast
+* What consideration must be made when designing for automatability? (including safety)
+* How can the system be automated?
+* 
+
+
+=============== Förslag till upplägg på resterande tid ===============
+1. Rapportskrivning, alla lediga stunder (48h?)
+2. Sätta ihop reläkort med dämpare (16h)
+3. Mäta upp dämpare i frekvensdomän och pulser (8h)
+-- Slut på allt praktiskt --
+4. Jämföra simulering mot uppmätt dämpare (8h)
+(5. Ta fram två algoritmer för att få parametrar från mätvärde (32h))
+(6. Jämför algoritmerna på ideal data och på riktig mätdata (16h))
+7. Färdigställ rapport (24h)
+
+150h ~ 4 veckor....
