Why power amplifier used in FM transmitter?
Amplifier is used in an FM transmitter to increase the level of a signal suitable for transmission
If the transmission bandwidth is doubled in FM then the SNR is?
decreases by 1/4
Which type of modulation is used in TV transmission?
In television system for video transmission AM is used and for audio transmission FM is used....
Why is frequency modulation preferred over amplitude modulation for transmission of music?
FM provides noise immunity, whereas AM is easily affected by noise. With FM, the amplitude of the sound is converted into a shift in frequency. So the volume is limited by the bandwidth, but the frequency of the sound can vary as much as it likes, giving a higher fidelity sound. Spikes induced on the signal usually affect the amplitude of the signal. The amplitude of an FM signal is not used in the demodulation process and is therefore immune to spikes in the signal. AM was first used in radio because it is very easy to achieve using basic components. A single rectifier only, is needed to recover the audio. FM is quite a complicated process and could only be achieved once electronics had progressed.
Why we need high power to generate AM signal and low power to generate FM signal?
The reason FM has lower power and AM has higher power is because the more power that an AM signal has, the farther it will go, but FM does not work that way. AM waves can bounce off of the atmosphere, especially at night. This is the reason that you can hear AM stations from far away at night. FM, on the other hand, can't bounce. FM waves only go in a straight line from the tower and no matter how much power you transmit with, an FM wave will only go a short distance. AM Waves can travel through trees and buildings, and FM can't.
What is the limitation of radio waves?
Radio is limited by its own design. AM & FM bands are frequency transmitted as radio waves. However since earth is round waves travels directly they do not bend. So as a rule the higher the frequency the more direct they are FM frequency is considered as line of sight transmission AM will have more range since it operates at lower frequency. At very low frequency it is possible to transmit around the earth by using the ionosphere curvature
What is the transmitting range of 10kw FM transmitter?
As FM is transmitted using VHF, the transmitting range is more a matter of Line of Sight than transmitter power as these frequencies only follow straight lines.
When was FM Consolidated line created?
FM Consolidated line was created in 1950.
What is the wireless technology that requires unobstructed line of sight between sending and receiving devices?
infraredvisible lightmicrowave beamtelevision and FM radio (the VHF & UHF bands)etc.
What is the Dembe FM studio line?
Dembe fm studio lines is +256785713128.
Why is the area of coverage for AM radio greater than FM radio?
The basic reason is that AM radio is broadcast on a lower frequency, while FM is broadcast on a higher frequency. And the lower frequency signals will curve around the earth a bit more than the higher frequency FM signals. FM is considered more "line of sight" than AM, which has that "fat" ground wave that hugs the earth a bit more.
Compare amplitude modulation and frequency modulation?
1)In FM the information signal changes the frequency of the carrier wave without changing its amplitude or phase whereas In AM the information signal changes the amplitude of the carrier wave without changing its frequency or phase.2)All transmitted power in FM is useful whereas in AM most of it is carrier which serves no useful purpose.3)FM has no signal-to-noise (S/N) ratio. It is due to two reasons: firstly, there happens to be less noise at VHF band and Secondly, FM receivers are fitted with amplitude limiters which remove amplitude variation caused by noise, whereas AM has signal-to-noise ratio4)Due to 'guard- band' there is hardly any adjacent-channel interference in FM whereas there is adjacent-channel interference in AM.5)Since only transmitter frequency is modulated in FM, only fraction of a watt of audio power is required to produce 100% modulation as compared to high power required in AM.6)FM requires much wider channel almost up to 20 times as large as needed by AM.7)FM requires complex transmitting and receiving equipment as compared to AM.8)Since FM reception is limited to only line of sight of propagation, area of reception for FM is much smaller as compared to AM.9)FM is used for FM broadcasting & in TV for video signal whereas AM is used for AM broadcasting & in TV for sound signal.10)FM transmission has higher fidelity as compared to AM transmission.
Do transmissions using radio signals require line of sight?
Yes, the line of sight is the direct free-space path that exists between two points. Using binoculars on a clear day, it is easy to determine if visual line of sight exists between two points that are miles apart
Why power amplifier used in FM transmitter?
Amplifier is used in an FM transmitter to increase the level of a signal suitable for transmission
Why does your FM radio purchased in Japan have limited frequency range when used in the US?
Japan use 76 - 90 FM
If the transmission bandwidth is doubled in FM then the SNR is?
decreases by 1/4
Can you use a mp3 player to listen to music on a radio via FM transmission?
Yes, you can, When you turn it on there should be applications (Mp3, Radio/FM, Options) Click on Radio/Fm and find your station.
