In an amplitude modulation with modulation index 0.5, the ratio of the amplitude of the carrier wave to that of the side band in the modulated wave is

Options

  1. A4 : 1
  2. B1 : 4
  3. C1 : 2
  4. D2 : 1

Correct answer

A. 4 : 1

Step-by-step solution

Modulation index, =0.5= 1 2 A_ S B A_C = 2 = 1 4 or A_C A_ S B = 4 1 or 4: 1
