A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.

If your old tv has no built in ATSC Digital Tuner , then you need a digital to analog converter box. This box receives the ATSC Digital Signal and converts it to NTSC Analog , for Tv's that only have a NTSC Analog tuner.
The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters. A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well. Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.
The only different is one has a needle, the other digital numbers-same as with analog and digital watches.
No a digital only phone will not work with analog service, but there are analog/digital phones, I don't know if these are still offered but they were very popular because during the transition from analog to digital, digital coverage was not as good as analog so when you had no digital service it would switch to analog. so the only way to have analog service is if the phone is dual analog/digital or if you have a old analog only phone. you can always look up your phone to see if analog is supported.
The only time you will be in need of a digital converter is if you currently own an analog television that is connected to an over-the-air antenna signal.
A digital audio jack serves the same purpose as an analog audio jack, only it transmits a signal that is digital (1s and 0s) instead of analog (waveform).
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.
No, you should not need a digital converter box anymore (unless you are still using an old analog television). Most digital televisions sold are capable of receiving both digital signals and the few remaining analog signals (permitted for very low power stations only at this time).
Only if the TV has a digital (ATSC) tuner. If it has an analog (NTSC) tuner only, it will not work with over-the-air digital broadcasts. In that case you'll need some sort of converter.
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
