Question

In a 16-ary PSK, the symbol rate is 10 kbps. The bit rate is ________.

• A. 160 kbps
• B. 40 kbps
• C. 2.5 kbps
• D. 0.625 kbps

Hint:

Bit rate = Symbol rate × log₂(M). For 16-PSK, 1 symbol = 4 bits.

Answer 1

The Correct Option is B

In M-ary PSK systems:
- Each symbol represents \( \log_2 M \) bits.
- For 16-PSK: \( \log_2 16 = 4 \) bits per symbol.
Given:
- Symbol rate = 10 kbps \[ \text{Bit rate} = \text{Symbol rate} \times \log_2 M = 10 \times 4 = 40 \text{ kbps} \]
