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.
15 maj 2024 · Amplitude Modulation or AM, is a modulation technology mainly used for radio carrier wave-based message transmission which modifies the carrier wave's amplitude (signal intensity) in accordance with the message signal, such as an audio signal, i.e., a modulating signal.
In the frequency domain, amplitude modulation corresponds to translating the baseband spectrum to a band surrounding the carrier frequency. Because the baseband spectrum is symmetrical with respect to the y-axis, this frequency translation results in a factor-of-2 increase in bandwidth.
Amplitude modulation (AM) is a modulation technique used in communication systems to transmit information through variations in the amplitude of a carrier wave. To achieve this, an AM system requires several crucial components, each serving a specific purpose. The first essential component of an AM system is the carrier wave generator.
This article describes how amplitude modulation (AM) is used to transmit audio information using radio frequency signals.
