In binary data transmission DPSK is preferred to PSK because

A a coherent carrier is not required to the generated at the receiver

B for a given energy per bit, the probability for zero is less

C the 180° phase shifts of the carrier

D more protection is provided against impulse noise

ANS:A - a coherent carrier is not required to the generated at the receiver
