    Salah satu cara memodifikasi/merubah Sinyal sehingga memungkinkan untuk membawa dan mentransmisikan informasi ketempat tujuan . Pengertian dari modulasi ...

    • A.

      FM

    • B.

      AM

    • C.

      PAM

    • D.

      FSK

    • E.

      ASK

    Correct Answer
    A. FM
    Explanation
    FM stands for Frequency Modulation. It is a method of modifying a signal by varying the frequency of the carrier wave in accordance with the amplitude of the input signal. This modulation technique allows for the transmission of information to the destination by changing the frequency of the carrier wave. Unlike AM (Amplitude Modulation), which varies the amplitude of the carrier wave, FM provides better signal quality and is less affected by noise. Therefore, FM is commonly used for high-fidelity music and speech broadcasting, as well as in applications such as two-way radio communication and television broadcasting.
