    Communication systems, 5th semester


    Assignment No. 4

    Posted On: 10-12-2018. Strict Deadline : 17th, Dec-2018

    Note: The assignment must be handover to the instructor in the class only. Late assignments
    will not be graded.

    1. Can intelligence be sent without a carrier? If so, how?


    2. Explain how you could transmit two independent baseband information signals by using SSB on a
    common carrier frequency.
    3. An AM signal with 100 percent modulation has an upper sideband power of 32 W. What is the
    carrier power?
    4. An SSB signal is generated by modulating a 5-MHz carrier with a 400-Hz sine tone. At the
    receiver, the carrier is reinserted during demodulation, but its frequency is 5.00015 MHz rather
    than exactly 5 MHz. How does this affect the recovered signal? How would a voice signal be
    affected by a carrier that is not exactly the same as the original?
    5. To achieve 75 percent modulation of a carrier of Vc = 50 V, what amplitude of the modulating
    signal Vm is needed?
