Amplitude modulation is the transferring of information onto a radio wave by varying the amplitude (intensity) of the radio carrier signal. Figure 1.6 shows that amplitude modulation involves the ...

but understanding the electronics behind modulation and demodulation of an FM signal can be confusing. We’ve covered the basics before, but FM is so tightly associated with broadcast radio ...

These radio waves represent a distinct part of the electromagnetic spectrum. There are many different types of radio receiver ICs. FM devices use frequency modulation (FM), a technique that causes the ...

Ham radio operators that ... and is more reliable than AM modulation. On the digital side, hams turned to different and more sophisticated digital transmission types with computers pushing ...
