What is the purpose of a coaxial cable?
The purpose of a coaxial cable is to act as a transmission line for a radio frequency signal. The electromagnetic field carrying that signal exists only in space between its inner and outer conductors.
What does tuning a radio station have to do with resonance?
A signal from a radio station is tuned in a radio receiver by applying the signal to a resonant tuned circuit that accepts the wanted signal while rejecting all the other signals arriving.
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
How does a radio signal go from a disc jockey speaking into a microphone at a radio station to your ear?
In the microphone, there is a diaphragm, which converts the DJ's voice into an electrical signal. This signal is sent along the wire to the antenna, which broadcasts it into the ether. Your home radio receives the signal through its aerial, then converts the signal from an electrical signal to audio - which is detected by your ear.
How are signal received in radio station?
transmissions
How many seconds does it take a radio signal to travel one parsec through space?
102,900,000
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
Who travel faster a radio signal or light in space?
They are the same physical phenomenon, with the same identical speed.
How radio signal works?
Your radio signal works by using its signal to go to a tower and back to your radio (Via antenna).
How far can a radio wave travel into space?
Radio waves can travel indefinitely through space until they dissipate or are absorbed by particles in space. The farthest man-made radio signal, the Voyager 1 spacecraft, has been transmitting radio signals back to Earth from over 14 billion miles away.
What was on the sputnik ships?
Essentially it was an orbiting satellite with a radio signal to let everyone else know the russians had got into space first.
Are there any researches done on aliens?
yes. one project was to send a radio signal into space and see if they got a reply. they did. it was alien.
What is the distance that a ham radio can travel?
The radio signal can travel to the moon, bounce off its face, and reach an operator on the other side of the world. You can even talk to the International Space Station!
Why might radio signals also be called radio waves?
A radio signal is essentially an electromagnetic wave in the radio section of the electromagnetic spectrum. Therefore, the radio signal is made of a radio wave.
What is the purpose of a coaxial cable?
The purpose of a coaxial cable is to act as a transmission line for a radio frequency signal. The electromagnetic field carrying that signal exists only in space between its inner and outer conductors.
