Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Digital modulation schemes represent binary data by modifying carrier properties.
Step 1: ASK (Amplitude Shift Keying) Changes amplitude of carrier to represent bits.
Step 2: FSK (Frequency Shift Keying) Changes frequency of carrier.
Step 3: PSK (Phase Shift Keying) Changes phase of carrier signal.
Step 4: Given condition Bits represented using phase shifts.
Step 5: Conclusion \[ \boxed{\text{PSK}} \]
Final Answer: \[ \boxed{(C)} \]
