A frequency division multiplexing system is used to multiplex 24 independent voice signals. Single sideband modulation is used for the transmission. Each voice signal is allotted a bandwidth of 4 kHz. What is the overall transmission bandwidth of the channel ? Correct Answer 96 kHz

Given,

Number of independent voice signals (N) = 24

Voice signal allotted bandwidth (SSB BW = Message BW = 4 kHz)

Transmission bandwidth = SSB BW × N

or, Transmission bandwidth = 4 × 24 = 96 kHz
