Frequency Modulation (FM) is a method of transmission that is commonly used in cabling systems. This method of transmission relies on the varying frequency of a carrier wave in order to transmit a signal. In this type of transmission, the frequency of the carrier wave is modulated or changed based on the signal that is being transmitted.
The FM transmission method is widely used in many different types of cabling systems, such as coaxial, fiber optic, and twisted pair cables. The most common application of FM transmission in cabling is for the transmission of audio signals. This method of transmission is also often used for the transmission of digital data, as well as for radio transmissions.
When using FM transmission in cabling systems, the signal is transmitted in the form of variations in the frequency of the carrier wave. This type of transmission has several advantages over other forms of transmission, such as increased range and improved signal quality. Additionally, FM transmission is also more resistant to interference and noise than other forms of transmission.
In order to use FM transmission in cabling systems, the carrier wave must be modulated by a signal. This modulation can be done with either analog or digital signals. In order to modulate the signal, the signal is either amplified or attenuated, depending on the type of signal. Once the signal has been modulated, it is then transmitted by the carrier wave.
FM transmission is a very popular method of transmission for cabling systems, due to its increased range and improved signal quality. Additionally, this type of transmission is also more resistant to noise and interference than other methods of transmission. As such, FM transmission is often the preferred choice for many types of cabling systems.
