The meaning of ‘am’ in Social Media is ‘ante meridiem amplitude modulation ‘.
Meaning of ‘am’
The term “am” has been used in social media for many years, mostly as a way to denote the time of day. In this context, it stands for ante meridiem, Latin for “before noon.” But did you know that “am” also stands for amplitude modulation?
Amplitude modulation (AM) is a type of analog radio broadcasting technology developed in the early 1900s. It was one of the earliest forms of radio transmission and is still used today in some parts of the world. AM works by modulating an audio signal or carrier wave with a message. The original audio signal is referred to as the “baseband” or “modulating” signal and the modified signal is referred to as the “sideband.”
When a transmitter sends out an AM broadcast, it first takes the baseband signal and applies it to an oscillator. The oscillator then creates a carrier wave with an amplitude that varies based on the strength of the baseband signal. This carrier wave is then sent out over a frequency band which is received by receivers tuned into that frequency band.
At its most basic level, when someone uses “am” on social media they are usually referring to ante meridiem which means before noon; however, they could also be referencing amplitude modulation which refers to a type of analog radio broadcasting technology.
Though it’s not widely known, amplitude modulation can be found in many everyday items such as cordless phones, walkie-talkies and even amateur radio systems. It’s also used extensively in aviation communication where AM is necessary for long distance transmissions due to its greater range than FM (frequency modulation). Additionally, AM can be used for digital data transmission allowing data streams up to 25 Mbps at low cost over long distances.
In conclusion, while most people know what “am” means when they see it on social media—ante meridiem, meaning before noon—many may not realize that “am” also stands for amplitude modulation; a type of analog radio broadcasting technology developed in the early 1900s and still widely used today in many applications such as cordless phones and aviation communication.
