Homework Equations
The Attempt at a Solution
I honestly don't know what to do here. I have tried to find a relevant equation in the chapter related to Communication system present in my textbook but I couldn't find anything useful. The solution uses the following formula:
$$P_T=P_c\left(1+\frac{m^2}{2}\right)$$
Where can I find the above formula?
Any help is appreciated. Thanks!
