Depth of modulation in terms of `E_(max)` and `E_(min)` is

Options

A. `m_(a)=(E_(max)+E_(min))/(E_(min))`
B. `m_(a)=(E_(max)-E_(min))/(E_(max))`
C. `m_(a)=(E_(max)+E_(min))/(E_(max)+E_(min))`
D. `m_(a)=(E_(max)+E_(min))/(E_(max)-E_(min))`

Answer

C

Explanation

`A_(max)=A_(c)+A_(m)`
`A_(min)=A_(c)-A_(m)implies mu=(A_(m))/(A_(c))=(A_(max)-A_(min))/(A_(max)+A_(min))`
