    Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal. … See more

    In electronics, telecommunications and mechanics, modulation means varying some aspect of a continuous wave carrier signal with an information-bearing modulation waveform, such as an audio signal which … See more

      Pulse-amplitude modulation (PAM) is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses. It is an analog pulse modulation scheme in which the amplitudes of a train of carrier pulses are varied according to the sample value of the message signal. Demodulation is performed by detecting the amplitude level of the carrier at ev…

        What is amplitude modulation, and what is an example?
        Amplitude Modulation is a simple method to transmit a signal, for example sound, from one end to another. A sound is a form of energy or vibrations. It travels in the air as waves. The nature of this wave is transverse. A wave has two important components: Amplitude and frequency. In Amplitude Modulation Amplitude of the carrier wave is changed ...

        What are some limitations of amplitude modulation?
        Disadvantages of Amplitude modulation: The most natural as well as man-made radio noise are too much of in this type of modulation. The AM receivers will not have any means to reject this kind of noise is to be generated. This modulation will require more than twice the amplitude-frequency to modulate the signal with a carrier.

        Why is amplitude modulation used for video signal?
        This strategy enables the video signal to be transmitted more efficiently through long distances. In general, video modulation means that a higher frequency carrier wave is modified according to the original video signal. In this way, carrier wave contains the information in the video signal.
