What is difference between modulated wave and carrier wave?

Carrier Wave:

A carrier wave is a high-frequency electromagnetic wave that is used as the "carrier" or the base signal in a modulation process.

It is typically a pure sine wave with a constant frequency and amplitude.

The carrier wave by itself does not carry any information; it serves as a vehicle to carry the information from one location to another.

In AM and FM radio broadcasting, the carrier wave is the primary signal transmitted by the radio station.

Modulated Wave:

A modulated wave is the result of combining the carrier wave with an information signal, such as an audio signal or data.

Modulation is the process of varying the characteristics of the carrier wave (either its amplitude or frequency) in accordance with the information signal.

There are two common types of modulation: Amplitude Modulation (AM) and Frequency Modulation (FM).

In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave.

In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave.

The modulated wave contains the information that needs to be transmitted, and it can be demodulated at the receiving end to retrieve the original information.

Why do radio stations repeat the news so often throughout the day?

For more than five decades, radio has played certain songs over and over because those were the songs people requested the most. Radio stations with a "top 40" format (the 40 top selling hits in the country) were designed to be almost like a jukebox, except they have personalities called disc jockeys who talk to you and also play the songs. Stations repeat the most popular songs in what is called a "heavy rotation"-- that is, the #1 song may repeat every hour and ten minutes, because that song is the one the most people are requesting and buying. To you and me, the repetition might seem boring, but people tune in at different times, and when they do, they want to hear their favorite song.

Stations are always trying to get the most listeners, because the size of the audience determines how much money the station can charge advertisers for commercials. (Like them or not, commercials pay for the operation of most stations.) The good news is that not every station plays the same songs over and over-- there are a number of different radio formats, and each has its own version of rotation-- for example, in album rock and classic rock, stations will repeat an important song every two or three days; other songs might be repeated once a week, or even once a month. How often songs get repeated is determined by the station's format, and how many songs are on their official playlist. Top-40 and hit music stations tend to have smaller playlists, while jazz and classical and album rock tend to have larger playlists.

1999 neon new starter just clicks?

If you have already replaced the battery, then you have a few other things to look at.

  • It could be the starter itself
  • it could be the starter solenoid which might be integrated with the starter or mounted somewhere in the engine compartment. You can find it by tracing the thick positive wire (red - about the size of a finger) to where it goes. If it goes directly to the starter then the solenoid is integrated and more difficult to test
  • It could be the positive wire itself and is not making a good connection to the battery or starter/starter solenoid
  • It could also be the ground wire (Black - about the size of a finger). If this wire is not making a good connection from the battery to the engine block, it will keep the starter from working

I would start with the wires, making sure you have a good connection and then work your way to the starter. The clicking is usually a result of the starter not getting enough current to crank the engine.

Are cathode rays electromagnetic waves?

  • Cathode rays are not electromagnetic rays because the cathode ray is a beam of electrons that travel from the negatively charged to positively charged end of a vacuum tube, across a voltage difference between the electrodes placed at each end.
  • The electrode at the negative end is called a cathode; the electrode at the positive end is called an anode.
  • Since electrons are repelled by the negative charge, the cathode is seen as the "source" of the cathode ray in the vacuum chamber.

How are different sounds and pictures produced by radio waves?

radio waves are basically energy. This energy is sent in pulses that are basically binary code. Binary code is what computers think by. Is consists of zeros and ones. (10110100 etc.) This code is converted into each pixel of a picture, or each tone in music. It is complicated!

Who inventecd am radio waves?

It evolved- in tandem and in paralell with amateur or Ham radio. one can call Hugo Gernsback- who published all manner of radio and related hobby magazines- as in effect the founding father- Hugo also was a prolific science-fiction writer. The idea of bouncing radio signals off planets was suggested in sober language in his radio magazines as early as l927 ( the year Gina Lollobrigida rolled off the Lines, The Yankees were burning up the league- and the San Rafael went missing in action- exactly ten years BEFORE the much- better known Electra Project. Glug Glug.

How do you set the stations on a Saab radio?

On my 1995 SAAB I believe the way to set a radio station button was to 1.Manually tune in the station you want and 2.Press and hold the button you want to store the setting in. Hold the button for a few seconds...when the sound on the radio comes back on, the station is saved and you can release the button. Note if you release the button too quickly rather than saving the new setting you will go to the old setting on the button. Hope that helps, Paul.

Where is radio fuse in 2003 Chevy Tracker?

The fuse box is located under the dash on the drivers side, on the side. On the 2001 Chevy Tracker it is a 10amp fuse and it is marked DOM. To reset the radio or CD player pull the fuse out with a pair of needle nose pliers for 10 sec. and push it back in. This should reset the radio, clock and CD player.

What fuse controls the radio?

It varies from car to car. For example a 1998 Ford Crown Victoria will have it in a different location from a 1998 Chevrolet Impala, or even the same car of another year. So, we need to know the year, make, and model of the car. Also, if it is an add-on radio, the fuse may be an in-line fuse, that is, in a special holder made into a wire somewhere behind the radio itself. Additionally, there are usually 2 fuses to any radio. One provides radio power when you turn it on, and the other provides power all the time, even when the key is off, so the radio can retain information stored in it's memory such as radio station presets, clock, and even the last setting you had it on when you turned it off, like volume, and station it was set to. If the car has the original factory radio instaled, you should look into your owner's manual to see which fuses are listed for the radio. If you don't have your owner's manual, call the dealer. They can look it up for you.

What was georgia's first radio station?

How do you remove a radio from 91 Riviera?

you have to take off the front cover of dash witch means u will have to take off the cover under the lil over hang part and the screws from the sids of the dash and u will have to pull the climate control out witch is just a few screws near the rear of the c.c. and then there are i think 4 or 5 screws that hold the radio bracket in then one net on the rear of that bracket that holds the radio i give it a 3-10 on a difficulty scale but that is me i did mine in about 2.5 hours but i had to mod some parts cuz i bought the wrong ones

Radio waves and useful of radio?

how are radio waves be used- well they are used by sound waves like as in u can hear sond waves but radio waves is where you are in the car and u are listening for instance capital fm that is radio waves

Hope It Helped Hennddyyyy:) :D

Does water affect radio waves?

I have to be honest with you. Technically, the answer is yes. Any electromagnetic wave passing within the effective gravitational distance of a large mass, like the sun or a black hole, will bend slightly.

The effect, though, is so slight that it was never even noticed until about 100 years ago. Even then, it was only found because the Theory of Relativity predicted it, so some scientists went looking for it really hard. Otherwise, any discrepancy would have surely been attributed to a margin of error!

In everyday life, the Earth's gravity has no significant effect on radio waves. Our radio systems don't need to take into account its gravitational effect. But when it comes to detecting planets and stars millions of miles away, it certainly does matter.

How do you convert frequency from meters to megahertz?

"Meters" is not frequency. It's wavelength.

If you know the wavelength in meters, divide 300 by it, and the result is

the frequency in MHz.

If you know the frequency in MHz, divide 300 by it, and the result is the

wavelength in meters.

Why does a radio go off when you unplug it?

If you have a radio like most people it is using the electricity from your outlet. When you unplug it, you disconnect it from the electricity and it cannot function. Unless your radio uses unicorn tears to run. In which case you are probably better off asking your local wizard.
