FM Meaning and
Definition
-
FM stands for Frequency Modulation. It is a method of transmitting audio signals by varying the frequency of a carrier wave. In FM, the frequency of the carrier wave is modified or modulated in a way that corresponds to the changes in the audio signal. This modulation technique allows for the reproduction of high-fidelity sound by minimizing noise and interference.
FM is commonly used in radio broadcasting due to its superior sound quality compared to other modulation techniques. It provides a wide frequency range and a strong resistance to signal degradation, making it suitable for both music and voice transmissions. FM radio receivers are widely available and can pick up FM signals within a specific frequency band.
The FM band, which ranges from 88 to 108 megahertz (MHz), is allocated for FM radio broadcasting. Each station on the FM band is assigned a unique frequency to prevent interference between different broadcasts. FM signals are transmitted using antennas, with higher antennas providing a larger coverage area.
Apart from radio broadcasting, FM is also used in various applications such as two-way radio communications, television sound transmission, and satellite communications. It is known for its ability to provide clear and consistent signals, making it a reliable modulation technique for a wide range of audio transmissions.
In summary, FM is a modulation technique that varies the frequency of a carrier wave in order to transmit high-fidelity audio signals. It is widely used in radio broadcasting and other communication systems for its superior sound quality and resistance to noise and interference.

Etymology of FM
The word "FM" stands for "Frequency Modulation", which refers to a method of encoding information on a carrier wave by varying its frequency. The etymology of the term can be broken down as follows:
1. Frequency: The word "frequency" originated from the Latin word "frequens", meaning "frequent" or "crowded". It evolved through French and Middle English to refer to the rate of repetition of a cyclic or periodic event.
2. Modulation: The word "modulation" comes from the Latin verb "modulare", meaning "to regulate" or "to measure". It entered the English language in the 16th century, referring to the act of adjusting or controlling something according to certain standards.
In the telecommunications context, the term "Frequency Modulation" was coined in the early 20th century to describe a method of transmitting signals using variations in the frequency of a carrier wave.
