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 … Meer weergeven 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 … Meer weergeven The carrier wave (sine wave) of frequency fc and amplitude A is expressed by $${\displaystyle c(t)=A\sin(2\pi f_{c}t)\,}$$. The message signal, such as an audio signal that is … Meer weergeven The RF bandwidth of an AM transmission (refer to figure 2, but only considering positive frequencies) is twice the bandwidth of the modulating (or "baseband") … Meer weergeven Amplitude modulation was used in experiments of multiplex telegraph and telephone transmission in the late 1800s. However, the practical development of this technology is identified with the period between 1900 and 1920 of radiotelephone transmission, … Meer weergeven A useful modulation signal m(t) is usually more complex than a single sine wave, as treated above. However, by the principle of Fourier decomposition, m(t) can be expressed as the sum of a set of sine waves of various frequencies, amplitudes, and phases. … Meer weergeven The AM modulation index is a measure based on the ratio of the modulation excursions of the RF signal to the level of the … Meer weergeven Modulation circuit designs may be classified as low- or high-level (depending on whether they modulate in a low-power domain—followed by amplification for transmission—or in the high-power domain of the transmitted signal). Low-level … Meer weergeven WebAmplitude modulation (AM) communication systems arose from the need to send an acoustic signal, a “message”, over the airwaves using a reasonably sized antenna to …
