CPM has
A. Narrower bandwidth
B. Wider bandwidth
C. More bandwidth requirement
D. None of the mentioned
I had been asked this question in class test.
I would like to ask this question from Receiver Synchronization in section Synchronization of Digital Communications
Correct choice is A. Narrower bandwidth
For explanation I would say: The increase in smoothness in the signals concentrate the signal energy in a narrower bandwidth, reducing the amount of bandwidth required.
