Multiple choice

If digital data rate of 9, 600 bps is encoded using 8-level PSK method, modulation rate is

  1. 1, 200 bands

  2. 3, 200 bands

  3. 4, 800 bands

  4. 9, 600 bands

B Correct answer
Explanation

For M-ary PSK modulation, the baud rate equals data rate divided by log2(M). With 8-level PSK, log2(8) = 3, so 9600 bps / 3 = 3200 baud. The answer correctly calculates the modulation rate.
