An amplitude modulated wave is represented by, vAM = 4 (1 + 0.2 sin 3

1.	An amplitude modulated wave is represented by, vAM = 4 (1 + 0.2 sin 314 t) sin (314 × 102t) The minimum and the maximum amplitude of the amplitude modulated wave will be respectively equal to, (1) 0, 1 units (2) 0, 4 units (3) 3.2 units and 4.8 units (4) 1.6 units and 8 units
Answer» Correct option: (2) 0, 4 units Explanation: V_c = 4 Modulated Index = m = 0.2 Minimum amplitude = 4(1 – 0.2) = 3.2 V Maximum amplitude = 4(1 + 0.2) = 4.8 V

Answer»

Correct option: (2) 0, 4 units

Explanation:

V_c = 4

Modulated Index = m = 0.2

Minimum amplitude = 4(1 – 0.2) = 3.2 V

Maximum amplitude = 4(1 + 0.2) = 4.8 V
