... Our goal is to use the diodes as rectifiers for AC-to-DC voltage conversion at high frequencies. To evaluate their performance we built a half-wave rectifier and measured the DC output voltage (Vout _DC ), while varying the frequency of an input voltage source (Vin ) with a 4 V peak amplitude [Fig. ...

Superheterodyne receiver



In electronics, a superheterodyne receiver (often shortened to superhet) uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. It was invented by US engineer Edwin Armstrong in 1918 during World War I. Virtually all modern radio receivers use the superheterodyne principle. At the cost of an extra frequency converter stage, the superheterodyne receiver provides superior selectivity and sensitivity compared with simpler designs.
