False.
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.
Explain how a Microwave regenerate signal about every thirty-five miles?
Microwaves travel in straight lines known as "line of sight." As they travel, they weaken due to atmospheric absorption and obstacles such as buildings or mountains. Regeneration stations placed approximately every 35 miles re-amplify and boost the microwave signal to maintain its strength and integrity over long distances.
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.
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.

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.
Is there a taxi rank at Victoria station?
There is a taxi rank at every main station in London, including Victoria.
Where is kebab found?
At every subway station in Berlin.
What is the station phone number?
That is going to be different for every firestation everywhere. In the US, it is usual to dial 911 in the event of an emergency, and give the information to the operator who can dispatch the appropriate emergency workers to you.
