[T]he wireless already depended on a wave system as the medium; how could another wave system (the signal) be carried by the wave system of the medium? Reginald Fessenden, a Canadian, was one of the first to solve this problem. His idea was to superimpose the signal wave on the carrier wave: to modulate the carrier wave. This is the basic concept of radio and television. Since there are two variables associated with a wave—amplitude or strength, and frequency or wavelength—there were two possibilities for modulation: hence the current AM (Amplitude Modulation) and FM (Frequency Modulation) systems of broadcasting.
