npub1qzxuwwcf5zlpnr0ev5rjev0mw74msvdgknxw6acwsjm0ppuxtvsswqwjhy (npub1qzx…wjhy) I always learn something new (or learning that something is not so new) from the Rad Lab series. The last time I looked, I learned that thermal methods for TrueRMS voltage and RF power measurements were already in wide use by WW2 engineers (before they were commercialized in the 1970). I thought about rebuilding a modern version of this WW2 circuit using SMD parts.
