A. PIA
B. PSK
C. PM
D. PM
E. None of the above
Answer: Option B
Solution(By Examveda Team)
Phase-shift keying (PSK) is a method of digital communication in which the phase of a transmitted signal is varied to convey information. There are several methods that can be used to accomplish PSK. The simplest PSK technique is called binary phase-shift keying (BPSK). It uses two opposite signal phases (0 and 180 degrees).Source : techtarget.com
