What is the frequency and wave form of old land line phone carrier?
First answer.The landline phone has no carrier frequency it is a baseband signal with a 3KHz bandwidth.Correction:So there is a signal that can handle a 3KHz bandwidth, what do you call that signal? I call it a carrier, if you don't have a carrier, you will need to amplify the audio every 30 meters else you will end up with no audio at the end of the line. So there is a carrier on all phone lines. Note the carrier signal are up to 90 VPP and is AM modulated at the instrument, but in digital systems the carrier are switched on and of, FSK modulation.
If the frequency in AM does not change then how are these sidebands formed?
The process of changing the amplitude of the "carrier" so as to add information to it (modulation) doesn't change the frequency of the carrier. But it does create energy at two other newfrequencies.The new frequencies are equal to (carrier frequency) plus and minus (the modulating frequency). These are referred to as the upper and lower sidebands.The upper sideband is an exact copy of the modulating signal, but with every component of it shifted up by an amount equal to the carrier frequency. The lower sideband is a mirror image of the upper sideband, with every frequency component in it reflected about the carrier frequency.
Why petrol station in Malaysia roof flat?
Petrol station in Malaysia roof flat because need to stop from burning. If heat can be inside, there will be much danger of possibly. Fire will to destroy many. But if petrol station roof flat then has chance not to inchange spark fire for not to come to life. Flat helps for keep every balance.
Why does every radio station have a different carrier frequency?
That's not exactly true. Any frequency you choose has several radio stations on it,but just not in the same city.Frequency is what your radio uses to separate the individual stations. If two stationsin the same city transmitted on the same frequency, your radio couldn't separate them.When you tuned to that frequency, you'd hear both of them at the same time, and youcouldn't understand either one.Listen to the 27 MHz 'Citizen's Band' some time.
What are the key components to every robot?
5 major components to every robot : which are a body structure, a muscle system to move the body structure, a sensory system that recieves information
To get information into its carrier wave every radio station has to amplify the carrier wave.?
False.

Explain how a Microwave regenerate signal about every thirty-five miles?
-- A receiver receives the radio signal from the previous station.-- The receiver extracts the information from the signal.-- The information is applied to a transmitter, which transmits a new radio signal to the next station.

How is a radio signal transmitted and received?
A broadcasting radio station has to generate and transmit (send out) carrier signals from its transmitters. A carrier signal has to be used because it is impractical to send out sound waves of energy over the very long distances used for radio broadcasting. If, for example, a station broadcasts on a radio frequency of 455 kHz, before it is transmitted by the station's radio transmitters, that carrier signal first has to be modulated with the sounds coming from the station's studio. The modulation method used can be either amplitude modulation (AM), frequency modulation (FM) or digital (DAB). DAB is short for "digital audio broadcasting". At the radio receivers used by the station's listeners, the modulated carrier signal is received through their aerials and then has to be de-modulated to release the studio sound. De-modulation can be described very simply as "removing the carrier signal to produce the sound". That sound then has to be amplified so that it can be listened-to using loudspeakers or headphones. The actual carrier frequencies used by a particular station have to be varied: 1) to suit their transmitters' locations 2) to suit the areas to be covered by that station's broadcasts and 3) to avoid causing interference with other radio stations. In every country there is a government agency which controls the particular frequencies which can be used by each station that broadcasts in that country. The fair use of all the frequencies available for broadcasting worldwide is co-ordinated and administered by part of the United Nations organisation - the ITU (International Telecommunications Union) - and its members are representatives from all countries worldwide.
When will be collision takes place in Network Switch?
Collision hardly takes place in todays intelligent switches. According to my knowledge all swicthes in todays era are working on CSMA-CD i.e. Carrier Sense multiple access - collision detection. Every station in a network sense the carrier so the switch before maintaining any communication.
What radio station is Lady Gaga on?
Her music is played on almost every radio station. =)
Does every city have a local 'Fox 5' news station?
Researching the Fox 5 news station has shown that this station is available in a wide range of cities throughout the United States. It has been found that this station is not available in every city.
Why don't trains stop at every station along their route?
Trains don't stop at every station along their route to save time and make the journey more efficient. Stopping at every station would significantly increase travel time and disrupt the overall schedule.
Where is kebab found?
At every subway station in Berlin.
