  • question_answer 8) A message signal of frequency \[{{\omega }_{m}}\]is superposed or a carrier wave of frequency \[{{\omega }_{c}}\]to get an amplitude modulated wave (AM), The frequency of the AM wave will be

    A) \[{{\omega }_{m}}\]                         

    B) \[{{\omega }_{c}}\]

    C) \[\frac{{{\omega }_{c}}+{{\omega }_{m}}}{2}\]             

    D) \[\frac{{{\omega }_{c}}-{{\omega }_{m}}}{2}\]   

    Correct Answer: B

    Solution :

    In amplitude modulation the frequency of modulated wave is equal to the frequency of carrier wave. Thus option [b] is correct. Hence, the correction option is [b].
