Question
12 signals each band limited to 5kh are to be transmitted by frequency -division multiplexer. If AM-SSB modulation guard band od 1kHz is used then the bandwidth of multiplexed single is
Options
A.101kHz
B.99kHz
C.84kHz
D.71KhZ
Solution
Total signal B.W = 12 × 5 = 60KHz
11guard band are required between 12 signal
∴ guard band width 60 + 11 = 71 kHz
11guard band are required between 12 signal
∴ guard band width 60 + 11 = 71 kHz
