This infrared detector can be used to detect the presence of modulated infrared signals in its vicinity from any electronic source, for instance, an IR handheld remote controller. It can also be used ...

The following is excerpted from Chapter 8 from “RF Circuit Design, 2e” by Christopher Bowick. The fundamental operation of an RF front end is fairly straightforward: it detects and processes radio ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
