    Question

    Generation of noise when one signal has higher strength

    than other while signal propagates in a medium
    A Attenuation Correct Answer Incorrect Answer
    B Dispersion Correct Answer Incorrect Answer
    C Noise Correct Answer Incorrect Answer
    D Distortion Correct Answer Incorrect Answer
    E All of these Correct Answer Incorrect Answer

    Solution

    Distortion : It means change in the shape of signal. This is generally seen in composite signals with different frequencies. Each frequency component has its own propagation speed travelling through a medium. Every component arrive at different time which leads to delay distortion. Therefore, they have different phases at receiver end from what they had at senders end.
