In BPSK, the ________ of constant amplitude carrier signal is switched

1.	In BPSK, the ________ of constant amplitude carrier signal is switched between two values according to the two possible values.(a) Amplitude(b) Phase(c) Frequency(d) AngleThis question was addressed to me in final exam.My question comes from Linear Modulation Techniques topic in chapter Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Correct answer is (b) PHASE The best I can explain: In binary phase shift keying (BPSK), the phase of a constant amplitude CARRIER signal is switched between two possible values m1 and M2. These two values corresponds to binary 1 and 0 RESPECTIVELY.
