A) \[10%\]
B) \[25%\]
C) \[50%\]
D) \[75%\]
Correct Answer: B
Solution :
[b] For given transmission band \[88-108\text{ }MHz\] \[{{\left( \Delta f \right)}_{\max }}=75\,kHz\] given \[{{\left( \Delta f \right)}_{actual}}=18.75\,kHz\] \[\therefore \] % modulation \[m=\frac{{{\left( \Delta f \right)}_{actual}}}{{{\left( \Delta f \right)}_{\max }}}\times 100=\frac{18.75}{75}=25%\]
