... Figure 2 illustrates a Sin wave at 4Hz. Notice that the horizontal axis is time, and is expressed in seconds. You can count the number of times the wave cycles, and you’ll see that it’s 4, ie: 4Hz. Given the frequency, you can easily find the wave period. For example, if the wave cycles itself 4 tim ...

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.
