Kijan estasyon radyo emisyon FM ap travay?

Radyo FM te kase nan lavi yo nan anpil moun epi li se fòm ki pi lajman itilize nan emisyon. Yo difize tout kalite pwogram son nan estasyon radyo pou pote moun lajwa lavi yo. Sepandan, èske w konnen ki jan estasyon radyo a anrejistre son sa yo epi fè pwogram nan son nan radyo a? Atik sa a pral di w repons lan nan.

 

What Is FM Radio Station ?

 

FM radio station is a collection of equipment, which contains one or more Ekipman difizyon radyo FM. It will cover the radio signal to a geographical area to achieve the purpose of sound communication with the user's equipment. There are many forms of FM radio, such as professional city radio, community radio, drive in service, private radio, etc. Generally speaking, a complete FM radio station package will contain the following equipment:

   

  • An FM transmitter
  • A professional FM dipole antenna
  • 20m coaxial cable with connectors
  • An 8-way mixer
  • Two monitor headphones
  • Two monitor speakers
  • An audio processor
  • De mikwofòn
  • Two microphone stands
  • Two microphone BOP cover
  • Other required accessories

  

Through these devices, the sound is transformed step by step, transmitted, and finally received and played by the user's radio. In these devices, FM transmitter, FM emisyon antèn, cable and audio line are necessary, and a radio station can not live without them. Other devices need to decide whether to add to the broadcasting station according to the specific situation.

 

How they work together ?

 

In the equipment mentioned above, FM broadcast transmitter is the most important electronic device, and other electronic devices work around it. Because FM broadcasting transmitter is not only an electronic equipment for broadcasting radio signals, but also because of this, FM broadcasting transmitter also determines the performance of radio broadcasting stations to a great extent.

 

Travay frekans

 

The working frequency of the transmitter determines the frequency position of the radio station. For example, if the transmitter transmits the radio frequency at 89.5 MHz, the frequency position of the radio station is 89.5mhz. As long as the radio is turned to 89.5mhz, the audience can listen to the program of the radio station.

 

  

At the same time, the frequency range of the transmitter is different, because the commercial FM frequency band allowed by each country is different. Most countries use 88.0 MHz ~ 108.0 MHz, while Japan uses 76mhz ~ 95.0 MHz frequency band, and some countries in Eastern Europe use 65.8 - 74.0 MHz frequency band. The operating frequency of the transmitter you buy needs to meet the commercial frequency band range allowed in your country.

 

K ap travay pouvwa

 

The power of the transmitter determines the coverage of the radio station. Although the coverage of the radio station is affected by many factors, including the power of the transmitter, the installation height of the antenna, the gain of the antenna, the obstacles around the antenna, the performance of the FM receiver and so on. However, the coverage can be roughly estimated according to the power of the transmitter. This is the test result of fmuser's engineers. Under specific conditions, transmitters of various powers can reach such a coverage, which can be used as a reference to help you select the power of the transmitter.

 

Travay Pwosedi

 

FM radio station does not work by a single electronic device. Although FM broadcast transmitter is the most important electronic equipment, it needs the cooperation of other electronic equipment to complete the normal broadcast content normally.

  

 

The first is broadcast content production - broadcast content is to create sound content, including the voice of the announcer, or the staff put the recorded broadcast content sound into the computer. For professional radio stations, they may also need to use mixers and sound processors to edit and optimize these sound contents to obtain better broadcast contents.

  

 

Then there is sound input and conversion - the edited and optimized sound is input into the FM broadcasting transmitter through the audio line. By means of FM modulation, the transmitter converts the voice unknown to the machine into an audio signal that can be recognized by the machine, that is, the electrical signal representing the audio with current change. If the transmitter is equipped with DSP + DDS technology, it will digitize the sound signal and improve the sound signal quality.

  

  

Broadcast and reception of radio signals - FM broadcast transmitter transmits electrical signals to the antenna, converts them into radio signals and propagates them. A receiver within its coverage, such as a radio, receives radio waves from the antenna and converts them into electrical signals for transmission to the receiver. After processing by the receiver, it will be transformed into sound and transmitted. At this point, the audience can hear the sound of the radio station.
