Multiple choice

If digital data rate of 9600 bps is encoded using 8-level phase shift keying method, the modulation rate is

  1. 1200 bauds

  2. 3200 bauds

  3. 4800 bauds

  4. 9600 bauds

B Correct answer
Explanation

For 8-level PSK, each symbol represents log2(8) = 3 bits. The modulation rate (baud rate) = bit rate / bits per symbol = 9600 / 3 = 3200 bauds.
