Topic: Electronics Engineering
The advantage of differential PSK (DPSK) over coherent PSK is
- A. DPSK requires less bandwidth compared coherent PSK
- B. DPSK receiver design is simple compared to coherent PSK
- C. DPSK Bit Error rate is lower than coherent PSK
- D. For same bandwidth, DPSK bit rate is higher compared to coherent PSK
Answer: A. DPSK requires less bandwidth compared coherent PSK
Explanation: Note: The provided key marks (a) as the answer. In standard literature, the primary advantage of DPSK is a simpler receiver design (b) as it avoids carrier recovery.
