Show answer & explanation
Correct answer: A
Solution: determine bits per signal and number of signal levels.
Step 1: Calculate bits per signal (bits per symbol). Divide the bit rate by the baud rate: 8000 bps ÷ 1000 baud = 8 bits per signal.
Step 2: Calculate the number of distinct signal levels. The number of levels M = 2^(bits per signal) = 2^8 = 256.
Answer: The signal uses 256 distinct signal levels and carries 8 data bits in each signal element.
