Carrier power is the power that comes out of a transmitter and goes to the transmitting
antenna at the moment when no information is being added to the transmission ... no
music, voice, sound, picture, data, noise, hum, no nothing. Only what they call a "bare
carrier".
There are different methods of adding information to the carrier, called "modulation".
Some of them change the instantaneous power of the transmitter, others don't.
Examples: AM rapidly varies the transmitter power. Properly adjusted FM doesn't.

What does a radio transform waves into?
Sound.More informationAfter a modulated carrier signal has been received through the radio's aerial, the radio de-modulates it to release the live sound as picked-up from microphones in the radio studio (or was taken from recordings), which was then used to modulate the carrier signal at the transmitter.De-modulation that is done by a radio receiver can be described very simply as "removing the carrier signal to produce the sound".
How do you send a digital radio signal to a FM radio?
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
What are the functions performed by carrier in radio communication?
THE FUNCTIONS ARE ; 1>in modulation process. 2>in inserting pilot carrier. ans. by arshid bhat kash....................
How does a wave carrier affect what you hear on the radio?
The carrier wave carries the information that you hear. It is modulated by the sound which varies its amplitude or frequency. Without the carrier there would be nothing to vary so you would hear nothing.
What is meant by am in radio?
Amplitude Modulation- AM standard Broadcast band. AM is an abbreviation for amplitude modulation,a form of radio transmission in which the carrier radio wave's amplitude is varied according to the strength of the modulating signal(sense).
Why do you need a carrier wave?
In radio transmission, you could theoretically transmit radio signals at audio frequencies. However, because the wavelength of electromagnetism at audio-like frequencies is Huge and the frequency of a radio transmitter dictates the size of the antenna and the power requirement, you would need A Very Big Antenna and a Very Big Power Supply to do this. So, we've learned to transmit at higher "carrier" frequencies, modulating either the amplitude or frequency of the carrier signal with our audio and subtracting the carrier at the receiver end.
Relation between total power and carrier power?
Total Power = Carrier Power * 5
To get information into its carrier wave every radio station has to amplify the carrier wave.?
False.
To get information into its carrier wave every radio station has to amplify the carrier wave?
False.
Why Need for carrier frequency stability?
Explain the need for carrier frequency stability in radio transmitters?
What difference between amplitude modulation and double sideband suppressed carrier?
Both are forms of AM but in suppressed carrier a filter is used to attenuate the carrier frequency prior to transmission. This is usually done to reduce the total transmitter power consumption. An ordinary AM radio cannot correctly receive suppressed carrier stations, you must have a receiver that replaces the carrier prior to the detector stage.

What is the modular of radio transmitters?
generates carrier waves
Does the radio transmissions send what is known as a carrier signal?
yes
The specific frequency at which a radio operates is called?
carrier wave
What is the meaning of suppressed carrier in am?
radio an amplitude-modulated wave in which only the sidebands are transmitted, the carrier being removedhttp://dictionary.reference.com/browse/suppressed+carrier+modulation
