In _________ the phase of the carrier signal is shifted to encode data.
A)PSK
B)FSK
C)ASK
D)BFSK

Question

Quizplus · Accepted Answer

In PSK (Phase Shift Keying), the phase of the carrier signal is shifted to encode data. FSK (Frequency Shift Keying) involves changing the frequency of the carrier signal to encode data. ASK (Amplitude Shift Keying) involves changing the amplitude of the carrier signal to encode data. BFSK (Binary Frequency Shift Keying) is a type of FSK where only two frequencies are used to encode binary data. Therefore, PSK is the best choice as it is specifically mentioned in the question that the carrier signal's phase is shifted to encode data.
