If it is a very old TV, more than likely it contains vacuum tubes that have gone bad. Vacuum tubes work by deflecting electrons inside a glass tube. This requires the tubes to be heated, with a small internal heater. The tubes have to warm up for them to work. This process should only take a minute or two. If it is taking hours the heaters are bad, or they arn't getting enough power to warm the tubes properly.
A Digital Television (DTV) Converter Box is an electronic device that converts the new free over-the-air digital signal into an analog signal viewable on older "analog" television set. The digital to analog converter box connects your antenna or rabbit ears to your TV set. It will allow you to continue watching TV after February 17, 2009, the day the transition to "all digital" takes place. A digital to analog converter box will not give you a digital picture on an analog TV set. Analog TV sets using the set top boxes will show digital broadcasts, but not in the full picture quality of digital TV. However, your picture will be better than it was with the old analog signal. Technically speaking about picture quality: The reason the picture quality won't be as good on an analog TV set is because of the display resolution. Analog TV screens aren't designed to display the same level of picture quality and resolution that is found in the digital TV signal.
A; An analog oscilloscope will display a signal to a CRT the same principle as a TV can display movies
6 Megacycles in analog. This includes picture, sound and guard bands.
Analog TV:Analog (or analogue) television encodes television picture and sound information and transmits it as an analog signal: one in which the message conveyed by the broadcast signal is a function of deliberate variations in the amplitude and/or frequency of the signal. All systems preceding digital television, such as NTSC, PAL or SECAM are analog television systems. Digital TV:Digital television (DTV) is the sending and receiving of moving images and sound by discrete (digital) signals, in contrast to the analog signals used by analog TV.
Because it had so many more advantages than than analogue radio and tv. It has better sound quality, less interference...

The last broadcast on analougue technology was broadcasted on the 23 october 2012. The analougue was switched of a 11:30 on this date. Digital Switchover Northern ireland was the last region to switch over above is the time it took place!
Its a television with an analog tuner built in. It picks up analog signals.
It is not illegal not to switch. It's just if everybody else are switched to digital, you don't have anything to watch. Basically it used to be analog signal masts were sending out to your TV, nowadays it's (mainly) digital as it guarantees better quality. Soon you'll don't get analog signal anymore, so to watch TV you have to be digital.
A CRT (cathode ray tube) is an analog component. Images are created by continuously varying the electron beam current which in turn changes the intensity of the phosphor light output. Additionally, the beam is scanned from left to right and from top to bottom using analog drive circuitry. Most televisions and monitors that use them are also fully analog but be aware that there are also televisions and monitors that accept and display digital video signals.
Digital signals produce a higher quality picture and many programs can be broadcast on a single digital channel, whereas only one program can be broadcast on an analog channel
Only if you have a digital output on your cable box. If not, it'll end up being a digital signal, converted to analog and then reconverted by your TV back to digital. Besides, the digital changeover date is only for local television stations when they turn off their analog transmitters. This means that if you currently have cable or satellite with analog outp[uts, that aspect of it shouldn't change.
