Ten signals, each requiring 3000Hz, are multiplexed onto a single channel using FDM. How much minimum bandwidth is required for the multiplexed channel? Assume that the guard bands are 300 Hz wide.
Show answerHide answer
Correct answer: (C) 32,700
Explanation
Total bandwidth = 10 channels × 3000 Hz + 9 guard bands × 300 Hz = 30,000 + 2,700 = 32,700 Hz. Ten channels need only nine guard bands between them.
