Research papers 740 words (21 pages) radio waves essay - radiowaves are the oscillations of magnetic waves by varying the modulation to generate different signals which can be converted into information such as sound, video, or digital communication. • amplitude modulation – the amplitude of the carrier signal is controlled by the modulating signal – pitfall of am: channel noise can corrupt the amplitude easily.
Amplitude modulation or am as it is often called, is a form of modulation used for radio transmissions for broadcasting and two way radio communication applications although one of the earliest used forms of modulation it is still in widespread use today the first amplitude modulated signal was transmitted in 1901 by a canadian engineer named reginald fessenden.
