What does AM mean in COMPUTING

Amplitude Modulation (AM) is a type of radio broadcasting waves in which the amplitude of the broadcasted wave is varied by the signal that is being transmitted. The frequency of the wave remains constant, while the amplitude changes according to the modulating signal. This allows for transmission of information such as audio, video and data over a variety of distances.

Amplitude modulation works by varying the amplitude, or volume, of an electromagnetic wave at a radio frequency. The modulated waveform then encodes audio or other data on top of it and broadcasts it over long distances with relatively low power. A receiver can then decode this information and output it as sound or video.

One major advantage of using AM for transmitting signals is that it requires little power to send messages over long distances. Additionally, AM can provide more reliable transmissions compared to FM transmission due to its ability to reject noise from other signals or sources in its vicinity.

One drawback of AM related to noise interference is that when one signal overlaps another in terms of frequency, both signals may become distorted and less audible. Furthermore, AM suffers from reduced fidelity in comparison to FM modulation due to its inherently narrower bandwidths for transmitting content.

Yes, AM continues to be used extensively today as most countries' broadcasting infrastructure utilizes both AM and FM for transmission purposes. Additionally, digital versions of AM such as digital-amplitude-modulated wireless systems provide higher-quality results than traditional analog systems.

Yes, some technologies such as radar systems may benefit from using AM instead of FM due to its greater levels of accuracy and sensitivity when detecting objects in close proximity. Furthermore, shortwave transmitters often use AM since they require wider bandwidths in order to reach far-off destinations.

An amplifier amplifies weak incoming signals so they are easier for receivers on either end of a connection to pick up and decode accurately. By amplifying signals before they reach a receiver’s antennae, their quality increases substantially while their range reaches much farther than without amplification.
