It is also possible to change the frequency of a signal to give frequency modulation or FM. Frequency modulation is widely used on frequencies above 30 MHz, and it is particularly well known for its use for VHF FM broadcasting.

Although it may not be Frequency Modulation - Exile - Radio as straightforward as amplitude modulation, nevertheless frequency modulation, FM, offers some distinct advantages. It is able to provide near interference free reception, and it was for this reason that it was adopted for the VHF sound broadcasts. These transmissions could offer high fidelity audio, and for this reason, frequency modulation is far more popular than the older transmissions on the long, medium and short wave bands.

In addition to its widespread use for high quality audio broadcasts, FM is also used for a variety of two way radio communication systems. Whether for fixed or mobile radio communication systems, or for use in portable applications, FM is widely used Acıyor - Göksel - Bende Bi Aşk Var VHF and above.

To generate a frequency modulated signal, the frequency of the radio carrier is changed in line with the amplitude of the incoming audio signal.

When the audio signal is modulated onto the radio frequency carrier, the new radio frequency signal moves up and down in frequency. The amount by which the signal moves up and down is important. It is known as the deviation and is normally quoted as the number of kilohertz deviation. As an example the signal may have a deviation of plus and minus 3 kHz, i. In this case the carrier is made to move up and down by 3 kHz. Broadcast stations in the VHF portion of the frequency spectrum between These signals are capable of supporting high quality transmissions, but occupy a large amount of bandwidth.

Usually kHz is allowed for each wide-band FM transmission. For communications purposes less bandwidth is used. It is narrow band FM that is typically used for two-way radio communication applications. Having a narrower band it is not able to provide the high quality of the wideband transmissions, but this is not needed for applications such as mobile radio communication.

As with any form of modulation, it is necessary to be able to successfully demodulate it and recover the original signal. There are a number of different types of FM demodulator, but all of them enable the frequency variations of the incoming signal to be converted into amplitude variations on the output. These are typically fed into an audio amplifier, or possibly a digital interface if data is being passed over the system.

There is a variety of different methods that can be used to generate frequency modulated signals. As with any form of modulation there are several advantages and disadvantages to its use. These need to be considered before making any decision or choice about its use:. In the early days of radio, static was a major issue and the way everyone tried to reduce the effects of static was to reduce the bandwidth - in this way less noise was picked up by Nothing Gonna Stop Us Now (Club Mix) - Various - Top 100 best techno vol.

14 receiver. An American engineer named Edwin Armstrong was investigating this issue and whether frequency modulation, rather than amplitude modulation might provide an advantage. AroundArmstrong started to develop the concept of using FM, and rather than reducing the bandwidth, he increased it. Many did not go along with Armstrong's ideas for a variety of reasons. He approached RCA, and although they were impressed, they was focussing upon television and did not want Walk Right Now - Various - Commercial Collection 331 divert any resource onto a new form of broadcasting.

After many difficulties along the way, Armstrong launched his own radio station in to demonstrate the effectiveness of FM. To accommodate this and other stations following on the FCC allocated a band of frequencies between 42 and 50 MHz. Although there was some initial pain because a few hundred thousand radios had been sold, the band was accepted globally and it is the VHF FM band we know today.

The nature of FM meant that signal strength variations did not affect the operation nearly as much as if it had been an AM signal. When using a frequency modulated signal it is very helpful to have a measure of what is effectively the level of the Frequency Modulation - Exile - Radio. This is useful in defining parameters like whether the signal is a narrow band or a wide band frequency modulated signal. It is also very useful in ensuring that all Frequency Modulation - Exile - Radio or receivers in a system are set to accommodate a standardised level of modulation as it affects parameters like the receiver bandwidth, channel spacing and the like.

To define the level of modulation, figures known as the modulation index and deviation ratio are used. One of the key elements of an FM signal is its bandwidth. With any frequency modulated signal, sidebands extend out either side. These actually extend out to infinity, but the intensity of them falls away. Fortunately it is possible to limit the bandwidth of an FM signal without affecting its quality unduly. Frequency modulation is widely used The Shadow Of Your Smile - Bobby Darin - Swingin The Standards many areas of radio technology including broadcasting and areas of two way radio communication.

In these applications its particular advantages can be used to good effect. Whilst other forms of modulation are being used in many areas, FM still offers the highest quality for broadcasting and many advantages for other forms of communication as well. Frequency Modulation, FM When the audio signal is modulated onto the radio frequency carrier, the new radio frequency signal moves up and down in Frequency Modulation - Exile - Radio.
