The traditional diode AM detector is shown in Figure 1. This detector has to operate at zero DC potential, so if the source has a DC component, the R-C combination is needed to block the DC in the ...
A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...
It has been proposed that high-frequency detectors based on the so-called spin-torque diode effect in spin transfer oscillators could eventually replace conventional Schottky diodes due to their ...
