MCQ (More than One Correct Answer)

-0.6

In binary data transmission DPSK is preferred to PSK because

a coherent carrier is not required to be generated at the receiver.

for a given energy per bit, the probability of error is less.

the 180⁰ phase shifts of the carrier are unimportant.

more protection is provided against impulse noise.
