In AM modulation, a signal is modulated on a carrier wave such that maximum and minimum amplitudes are found to be 6 V and 2 V respectively. The modulation index is :

Multiple Choice Options

  • A 100%
  • B 80%
  • C 60%
  • D 50%

Step-by-Step Verified Solution

Amax = 6 V

Amin = 2 V

μ=Amax⁡−Amin⁡Amax⁡+Amin⁡=6−26+2=0.5\mu = {{{A_{\max }} - {A_{\min }}} \over {{A_{\max }} + {A_{\min }}}} = {{6 - 2} \over {6 + 2}} = 0.5

μ=50%\mu = 50\%
