how does a television works?

Answer 1

In an analogue colour television signal there is a black and white signal that can be picked up by a black and white television. The colour information is broadcast in a separate signal. All colours can be represented by a mixture of three colours in different proportions. The colour signal contains information about two colours mixed together in a clever way. The third colour is worked out by subtracting the first two colours from the black and white signal. In a television tube there are three electron guns firing at a screen with phosphoresent dots on it. Some dots glow red when electrons land on them some green and some blue. Each colour dot is arranged so that only one electron beam can shine on them. The electron beams are moved rapidly across the screen by magnetic fields and the intensity of the beams are varied by the red, green or blue signals. The red, green and blue pictures formed by the dots are combined by the eye to appear like normal colours.

Answer 2

The camera etc change a picture into electrics. These electrics are changed into elecronic radiation which is sent from an aerial out through the air. When this radiated signal reaches your aerial (or dish or whatever,) the opposite happens and your television turns the electrics back into pictures.
This is about the simplest explanation I can think of. If you need more, try wikipedia.

Answer 3

Televisions are an extremely mature classification of product. they are greater stable presently than they ever have been and individuals are keen to pay many hundreds or maybe hundreds of pounds for the final that they could have the money for. the priority with computers specifically with the aid of fact the laptop marketplace has bloomed interior the final decade or so and is greater value-gentle so maximum individuals (and companies) purchase the main inexpensive that they could get. This leads to a flood of very complicated machines (and all modern computers are very complicated bits of equipment) that are geared up to the backside obtainable fee and corners are cut back in layout and manufacture ultimate to aspects overheating and mechanical failures and so on. maximum machines use aspects from a limited style of aftermarket makers so which you would be fortunate to locate one form truly greater stable than yet another. subsequently, while in comparison with tellys they are truly "decrease priced and nasty" issues. If we've been keen to pay greater then the build high quality could be better - yet we will not do we.. desire this helps.

Signals are sent in to an electron transmiter that send electrons up into the Cathod ray tube, that then engergise a phosphorus screen at the end and this changes the colour in lines!
Well that is CRT tvs, then u have plasma and LCD(Liquid crystal display) these are lot more complex!
