INTENSITY MODULATION Meaning and
Definition
-
Intensity modulation refers to a method of modulation used in telecommunications and signal processing, where the intensity or power of a carrier signal is varied in order to convey information. In this modulation technique, the amplitude or power of the signal is varied proportionally to the amplitude of the modulating signal.
The process of intensity modulation involves the combination of a steady carrier signal with a modulating signal that carries the desired information. This modulation technique can enable the transmission of analog or digital data over a communication channel.
The modulating signal, which is typically an audio or video signal, is used to manipulate the amplitude or power of the carrier signal. The variations in the intensity of the carrier signal correspond to the changes in the modulating signal, allowing for the retrieval of the original information at the receiving end of the communication system.
Intensity modulation is widely implemented in various communication systems, including optical communication systems, radio communication systems, and television broadcasting. It provides an efficient and straightforward method of transmitting information using variations in the power or amplitude of the carrier signal.
Overall, intensity modulation plays a crucial role in a range of communication applications, enabling the efficient transmission of information by manipulating the intensity or power of carrier signals.

Etymology of INTENSITY MODULATION
The etymology of the word "intensity modulation" can be understood by breaking down the two individual words.
1. Intensity:
The term "intensity" originates from the Latin word "intensitas", which means "force" or "energy". It is derived from the verb "intendere", meaning "to stretch" or "to direct". Over time, the meaning evolved to represent the degree or strength of something.
2. Modulation:
The word "modulation" comes from the Latin verb "modulare", which means "to measure", "to melody", or "to regulate". It is derived from the noun "modulus", meaning "measure" or "standard". In physics and electronics, modulation refers to the process of varying a parameter or a characteristic of a wave, such as amplitude, frequency, or phase.
