All detector circuits are limited in their capability to differentiate ... At this point, it is sufficient to note that the AM diode detector architecture is limited in selectivity and sensitivity.

Using a diode as a detector, the design generally uses less ... right pads on the credit card to the rest of a crystal radio circuit, and you’re all set. Of course, [Billy] goes the whole ...

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 ...

From primitive crystal detectors to today's advanced exponential logarithmic amplifiers, RF power detection has come a long way.
