What does the number of a FM radio station mean?
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the signal.
What are Electromagnetic wave transmitted by a radio station called?
Radio stations that broadcast in the AM to FM range transmit EM waves known justly as radio waves (EM waves with frequencies from 30 KHz to 300 MHz, or wavelengths from 10 km to 1 m).
What does it mean to say that a radio station is at 103.6 on your FM dial?
It means that the radio station transmits on a carrier frequency of 103.6 MHz,and that if the 'dial' on your FM radio is properly calibrated, then you'll receivethat station best when you adjust your radio to indicate '103.6'.By the way... no legal FM station will ever say that, at least not in the USA, becauseall licensed FM broadcast stations in the US transmit on carrier frequencies that havean odd number after the decimal point. They can be on 103.5 or 103.7, but neveron 103.6 .
How many AM broadcast stations can be accommodated in 6 MHz bandwidth of each station transmits a signal which was modulated by an audio signal having a maximum frequency of 5 kHz?
-- So long as the AM modulation index doesn't exceed 100%, only one set ofsidebands exists, and the spectral width of an AM signal is double the highestmodulating frequency ... 10 KHz in this case.-- Dealing strictly with the arithmetic ...6 MHz/10 KHz = 600 AM channels in the equivalent of one analog TV channel.-- But 6 MHz of AM spectrum could never be used that way, because ordinaryconsumer-grade AM radios can't deliver a listenable program in the presence ofanother signal of equal nominal level on the adjacent channel. With all of theseAM stations all in the same metro area, you'd need to figure at least one guardchannel between adjacent AM stations ... reducing the capacity of your 6 MHzto no more than 300 stations, because of typical receiver quality (or lack thereof).-- Also, of course, notice that with 300 AM stations in one market, none of themcould sell any appreciable amount of commercial time, because none of them wouldhave any appreciable audience, and half of them would die in the first month.-- Finally, when you start thinking about commercial spectrum utilization, it'simportant to be aware that whereas this little exercise speaks in terms of theequivalent of one whole analog TV channel dedicated to AM broadcasting, theentire real-world AM broadcast band is barely 1/6th of that much ...530 KHz - 1700 KHz = 1.17 MHz !
What wave are received by car radio?
It depends what kind of station it is. If it's an analogue station - it transmits Frequency Modulated (FM) and/or Amplitude Modulated (AM) signals. If it's a digital station, it transmits digital 'packets' of data in FM format.
A device that transmits on one frequency and receives on another?
a transceiver
What is a radio that transmits and receive very high frequency?
A VHF transceiver.
Which frequency signal does the mobile phone transmits continuously?
None, as it doesn't transmit continuously.
What is a block Diagram of Cable TV?
Whether it is an analogue or a digital broadcast, a block diagram is the basic structure of a television broadcast. The is structure begins with the camera and mic, goes through the amplitude and frequency modulation phases, combines the video and audio, and transmits it out via a network tower or satellite.
What is divided in TDM multiplexing technique?
TDM means time domain multiplexing. One communication channel transmits for a short time, then another, then another. For example, in modern cell phones, up to 8 users share a frequency; each transmits for a few milliseconds at a time.TDM means time domain multiplexing.

Why do you hear outgoing message but not the incoming message when using a scanner ex EMS to hospital hear the hospital not EMS?
The are using a duplex frequency system where the base transmits on one frequency and listens on another AND the mobile units transmit on the freq the base listens on but listens on the freq the base transmits on.
Why does a telephone not do a very good job of transmitting music?
To expand on LincMad's statement: The frequency range of a voice-grade telephone circuit is 300 to 3100 Hertz. The frequency range of your stereo is 20 to 20,000 Hertz. They use the narrower bandwidth on a phone system so they can pack more phone calls into the same cable.A telephone transmits only a very limited range of audio frequencies, optimized for speech. Thus, all the high and low notes in music get lost over a telephone connection.
What type of scanning the station transmits a special frame known as a probe on all available channels within its frequency range?
active scanning
What waves are in bluetooth?
Bluetooth networking transmits data via low-power radio waves. It communicates on a frequency of 2.45 gigahertz. Cha Cha!
Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
What is direct brodcast?
Direct - direction - to point something at a specific object Broadcast - transmit - to send something from one place to someplace else or multiple places at the same time Direct Broadcast - directional transmission - to send something from one place to specifically someplace else and no where else Example: A radio/tv station transmits it's broadcast from its omnidirectional, or in every direct, antenna A multi-building company transmits it's network connection from one building to another with a directional antenna The advantage of direction broadcast is you can choose where the signal goes and thus who gets it. Also, it tacks less energy for a direction antenna to send the same information over the same distance and the omnidirectional antenna.
What are the services of WAN?
