Hi guy!

I found these nice problem on 'angle modulation' as you can see attached....

I would like to know if anybody recognise this book or help me find from which book this has been taken from??

Kindly regards, Eric007

 

I just googled "chapter 4 angle modulation" and got some good hits back.
