      I thought maybe you were going to add the second “P” in “Dropped” when the blooper at the end came in.

      The drop in order of magnitude is interesting in suppression of RF signals. Drops most off there in vestigial carriers.

      Eh, how many Fluke 87’s Dave exactly has? Half a dozen?

      • http://www.eevblog.com EEVblog

        two!

          Dang it…. My guess was off by an order of magnitude :(

          :)

      just look at in in dB, it’s less awesome. or not :)

      reminds me of some link budgets to mars spanning some 280 dB =28 orders of magnitude for power (14 for voltage) Plain crazy…
      look at that :

      Dave has +6dB a Fluke 87 :-)

      • f4eru

        And this also costs +6 dB$ :))

      What a bad blog. It didnt’t cover any advanced topics at all like:

      “Wholy f@#k the boss is going to kick my ass my caculations were out 10 orders of magnitude on that last design we did.”

      Or

      “I totally f&$ked up somewhere im out by many orders of magnitude”

      Start using these advanced use case’s and you’ll sound like someone who’s been in the industry in no time….

      (Disclaimer: Should you require to use these advanced usage’s of “orders of magnitude”, expressly no guarantee is implied or given as to the continuation of your employment)

      For cap and inductor values I just remember MUNP!
      m = milli = 10^-3
      u = micro = 10^-6
      n = nano = 10^-9
      p = pico = 10^-12
