1.1 Using a table of Bessel functions, determine the minimum bandwidth for the FSK signal from the previous problem (Problem 1.a). Remember that the significant bands are taken for those with amplitude > 1%. Since the table is normalized (Jo=1 at most), the significant sidebands are those with amplitude > 0.01). -- Indications: In your answer, place the result without the units and expressed in kilohertz

Amplitude modulation

A radio signal can carry information in the form of sound or image for broadcasting or communication. For it to be sent to a greater distance, the signal must be changed or modulated in some way. One of the easiest way is to change the amplitude of the signal with variations of the video or the audio signal. This is called Amplitude Modulaton. In this modulation information of message is carried in amplitude of carrier signal.
