If the maximum and minimum voltages of an A.M wave are V _ and V _ min respectively, Then the modulation factor ' m ' is
Options
- A( V _ + V _ ) ( V _ V _ )
- B( V _ - V _ min ) ( V _ + V _ )
- C2 ~V _ V _ ( V _ + V _ )
- D( V _ + V _ ) ( V _ - V _ )
Correct answer
B. ( V _ - V _ min ) ( V _ + V _ )
Step-by-step solution
Modulation factor of AM system is given by = V_ -V_ V_ +V_
