Q.

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. angle
Answer» B. phase
Explanation: 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.
