How coaxial cable transmit more than one television channel tell me the factors bandwidth for each channel?
It is just like radio through the air: lots of channels travel together through the mediumm (air) and don't (usually) interfere with each other. Officail (in the US the FCC does this) tables of frequency allocations set the spacing so interferance between channels doesn't occur. Radio signals can travel over copper wire even better than through the air. So a cable station effectively makes a tiny transmitter for each channel the customer receives, then combines all those signals and applies the combination signal to their end of the cable. The combined signal travels over the cable, aided by amplifiers that extend the distance, all the way to the customer's TV set. In the set, the tuner extracts the signal that you want to watch from the cable , it "tunes" in the signal out of all those that were combined, just the way it would tune in a station from an antenna in the air.
What else can I help you with?
In cctv why you are using coaxial cable?
Just as with television or satellite , this is to transmit video signals
Does coaxial cable improve tv picture?
Yes, coaxial cable can improve TV picture quality compared to other types of cables like RCA or composite cables. Coaxial cables have higher bandwidth capabilities, which allows for better transmission of high-definition signals with less interference. Additionally, coaxial cables are more shielded, reducing signal loss and noise in the transmission process, resulting in a clearer and sharper picture on your TV.
Can you connect a DVD without coaxial outlet to tv with coaxial connection?
you can buy a rf converter from radio shack or if you have a vcr you can run the rca cables to th e input on the vcr and output with coax.(make sure you turn the channel on the vcr to the video input channel
What is the purpose of a coaxial port and how is it used in electronic devices?
The purpose of a coaxial port is to transmit high-frequency signals with minimal interference. It is used in electronic devices to connect antennas, cable TV, and other devices that require high-speed data transmission.
How do you hook up a RF modulator and dvr?
To hook up an RF modulator to a DVR, start by connecting the DVR's audio and video output (usually composite or RCA cables) to the input of the RF modulator. Next, connect the RF modulator's coaxial output to your TV's coaxial input. Finally, set the TV to the appropriate channel (usually 3 or 4) that the RF modulator is configured to transmit on, and you should be able to see the DVR's output on the TV. Make sure all devices are powered on and properly configured for best results.
How do you hook up cable to a TV with a broken coaxial input but has the three AV inputs?
If your television has a broken coaxial input but has three AV inputs (Red, White, and Yellow), and your cable box has the same AV inputs in the back of it, which they usually do, all you have to do is connect the cords from the cable box to the TV(if you dont have the RCA cords, these can be purchased at any electronic store). Instead of putting your TV on channel 3 or 4 as you would when the cable is hooked up by coaxial, switch your channel to one of your Input or Video channels, as you would do if you were trying to watch a VHS tape or DVD. You'll see that the AV outlets provide just as good of a picture as the coaxial hookup.
What are the three network media and the signals they transmit?
The three main types of network media are twisted pair cables, coaxial cables, and fiber optic cables. Twisted pair cables, commonly used in Ethernet networks, transmit electrical signals. Coaxial cables also carry electrical signals and are often used in cable television and internet connections. Fiber optic cables transmit data as light signals, allowing for high-speed and long-distance communication.
What modem uses coaxial cable?
A coaxial cable has great uses in television antenna connections. TV satellite connections also use coaxial cables to connect decoders to the TV set.
What is the purpose of using a coaxial splitter?
The purpose of using a coaxial splitter is so that one can connect more than one device to a single coaxial line. For instance connecting two TV's to one coaxial line for cable television.
How do I watch old VHS tapes on old Sony TV?
To watch old VHS tapes on an old Sony TV, you'll need a VCR (Video Cassette Recorder). Connect the VCR to the TV using coaxial cables or RCA (red, white, and yellow) cables, depending on the available ports. Turn on the TV and set it to the appropriate input channel (usually channel 3 or 4 for coaxial, or the corresponding AV input for RCA). Insert your VHS tape into the VCR and press play to enjoy your videos.
Is cable internet faster than DSL?
This can be a complicated question, but in most cases cable is faster than DSL. Cable offers more bandwidth to more people than DSL, and the coaxial cables used to transmit data are much larger.
How do you fit an coaxial cable from main Ariel to tv?
If the aerial ends in a coaxial cable, connect an f-type end on the cable and screw it to the back of the tv.
