    Since this is your first post, I must inform you that All About Circuits isn't a free homework service.
    You must first post your efforts concerning the exercise in question, and then the AAC community will help you where you seem to have trouble

    Please post what you have done so far in order to solve the problem, no matter how wrong it might be.

    :D


    OP: Any standard text like B P Lathi deals with SSB generation.
    Ideally SSB is generated by passing a DSBSC signal through an ideal filter(low pass for LSB and high pass for USB).

    So simply you can design a circuit that generates DSBSC and a filter circuit(either LPF or HPF) and cascade the two blocks to get SSB. Since ideal LPF and HPF are not physically realisable your message should not have any components around DC(zero frequency).
