Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

The combination of electric and magnetic fields at right angles produces radio waves. These waves occur at different frequencies, and the range of useful frequencies is called the electromagnetic ...
