AM Full Form
Full Form of AM :
Amplitude Modulation
AM Full Form is Amplitude
Modulation, which is a radio broadcasting method. It was
perhaps the first way to impress sound over a radio signal. It has been one of
the most used methods of broadcasting till today. AM is also used for 2-way
radio communications. It was in 1901 that an Engineer from Canada transmitted
the first signal through amplitude modulation.
The primary concept of AM is very
simple and straight. Here, the signal’s amplitude is altered in accordance with
the sound intensity which aided the sound signal to be superimposed on the
radio signal. Thus, the radio signal becomes the ‘carrier’. The main reasons
why there has been continued usage of AM over many years are (1) AM can be
implemented without complications, (2) It can also be demodulated using a
simple circuit and few components, (3) Very cost effective. Nonetheless, AM has
a few disadvantages like high power usage, bandwidth, and noise interruptions.
