diode? edit

The rectifier diode is not so obvious as an example. The voltage should be proportional to the input (voltage) amplitude. On the other hand, most photodetectors generate a voltage output proportional to the input light power. That is, one photoelectron per photon, and is much more obvious. Detection of second-sound in superfluid helium is another example. Anything that converts input power to voltage should make a good example. Gah4 (talk) 22:25, 1 October 2019 (UTC)Reply
