television signals are communication signals, which can either be radio or microwave signals. These are both part of the electromagnetic spectrum. In the spectrum all the different signal types have some similar properties, including being able to travel through a vacuum, usually because they have a strong enough frequency and wavelength, and they don't need to travel in particles but waves :)
They are called as radio waves. They have got the speed of light. The wave length of the radio wave may be up to few kilometers.
A TV card is a kind of television tuner that allows television signals to be received by a computer. TV Tuners also function as video capture cards .
The peak wavelength of the IR diode used in TV remotes are usually around 940 nanometers.

Assuming you are talking about over-the-air television and you live in the United States, then no, it's not possible. Wifi networks use a spectrum of radio frequency much higher than the bands designated by the US Government for UHF television (and most TV networks have signals in the VHF band, which is even lower). Interference is a result of multiple signals competing on the same wavelength, or very near it, and that is simply not possible for over-the-air television, as it operates at a much lower frequency.
Egyptians, like the rest of the world, (Mexicans, Italians, Japanese, etc) receive over the air TV signals, satellite TV signals, and cable TV signals. So the answer to this astoundingly stupid question is YES!
Cable Television
If placed in the wrong location, wind turbines can affect radio and television signals.
what is the modulation used in telivision for audio signals
Satellite TV Providers transmits the signals through their satellite dish converting it first from digital signals to analog signals. These signals which were converted will be transmitted to the satellite. The satellite will then transmit the analog signals per request of the satellite dish connected to the receiver of the subscriber. Once signals are received, it will be converted back to digital signals which can be read by the receiver and be displayed to the television.
