Question:medium

A FDM system is used to multiplex 24 independent voice signals. SSB modulation is used for the transmission. Given that each voice signal is allotted a bandwidth of 4 kHz, calculate the overall transmission bandwidth of the channel?

Show Hint

For SSB transmission: \[ \text{Channel Bandwidth} = \text{Message Bandwidth} \] Therefore, \[ B_{Total}=N\times B_m \]

Updated On: Jun 25, 2026

\(6~kHz\)
\(8~kHz\)
\(96~kHz\)
\(192~kHz\)

Show Solution

The Correct Option is C

Match List-I with List-II:

List-I (Modulation Schemes)	List-II (Wave Expressions)
(A) Amplitude Modulation	(I) \( x(t) = A\cos(\omega_c t + k m(t)) \)
(B) Phase Modulation	(II) \( x(t) = A\cos(\omega_c t + k \int m(t)dt) \)
(C) Frequency Modulation	(III) \( x(t) = A + m(t)\cos(\omega_c t) \)
(D) DSB-SC Modulation	(IV) \( x(t) = m(t)\cos(\omega_c t) \)
