Amplitude Modulation

Write two basic modes of communication. Explan the process of amplitude modulation. Draw a schematic sketch showing how amplitude modulated signal is obtained by superposing a modulating signal over a sinusoidal carrier wave.

Both amplitude modulation (AM) and frequency modulation (FM) are used for radio broadcasting. The amplitude of the high frequency carrier wave is varied or modulated in accordance with the variations in the amplitude of the audio signals that are to be transmitted, in te process of amplitude modulation in frequency modulation te amplitude of the carrier remains constant but its frequency is varied inn accordance withh the audio signal. Reception with AM signals is in general is affected by interference of various kinds ad elaborated equipment is required for FM broadcast. A radio frequency carrier wave can be modulated using a-

Production Of Amplitude Modulated Wave

An amplitude modulated wave is as shown in figure . Then , the modulation index will be

An amplitude modulated wave is as shown in the figure. What is the percentage of modulation ?

An amplitude modulated wave is represented by the expression v_m=5(1+0.6 cos 6280 t) sin ( 211 xx 10^(4)t) volts. The miniumum and maximum amplitudes of the amplitude modulated wave are , respectively :

An amplitude modulated wave is modulated to 50% . What is the saving in power if carrier as well as one of the side band are suppressed?
