# A message signal of frequency 100MHz and peak voltage 100v is used to execute amplitude modulation on a carrier wave of frequency 300 GHz and peak voltage 400 v. The modulation index and difference between the two side band frequencies are : (a) 4 ; 2 × 108Hz (b) 4 ; 1 × 108Hz (c) 0.25 ; 1 × 108Hz (d) 0.25 ; 2 × 108Hz

## Question ID - 51334 :- A message signal of frequency 100MHz and peak voltage 100v is used to execute amplitude modulation on a carrier wave of frequency 300 GHz and peak voltage 400 v. The modulation index and difference between the two side band frequencies are : (a) 4 ; 2 × 108Hz (b) 4 ; 1 × 108Hz (c) 0.25 ; 1 × 108Hz (d) 0.25 ; 2 × 108Hz

3537

Range of frequency = (fc − fm) to (fc + fm)

Band width =  = 2 × 100 ×106 Hz

= 2 × 108Hz

And modulation index =  =
