    The audio signals of TV are –

    A Amplitude modulated Correct Answer Incorrect Answer
    B Frequency modulated Correct Answer Incorrect Answer
    C Unmodulated Correct Answer Incorrect Answer
    D Velocity modulated Correct Answer Incorrect Answer

    Solution

    In analogue television, the sound portion of a broadcast is invariably modulated separately from the video. Most commonly, the audio and video are combined at the transmitter before being presented to the antenna, but in some cases separate aural and visual antennas can be used. In almost all cases, standard wideband frequency modulation is used.
