Do crystal radio sets still work now that everything has gone digital?
Yes because only television signals from some stations have gone digital. Crystal radios will pick up stations broadcasting on the A.M. broadcast band (540k to 1600K). These signals are amplitude modulated and crystal radios pick these up really well. You could also use them for Shortwave and pick up some stations. Am, FM and shortwave are still not digital.
Describe the steps involved in installing a cable?
In general in new houses, "jacks" will be pre-installed. The engineer will run a cable from the jack to the tv. The television then has to be programmed and auto-tuned to pick up the signals.
What is the scientific principle for tv?
Most simplistically, it works on radio waves, invisible wave lengths that can be picked up by receivers and translated into electronic signals that control displays on a "picture tube". Most recently, digital signals have replaced analog waves, and of course many people are now receiving the electronic TV digital signals via cable, rather than by air-waves. TV's, unlike just a radio, need to have a video tube, and an electronic tuner to put "color" pixels onto a screen of some sorts (plasma, or LCD's are more common today, than old picture tubes)
What happened to all the TV rabbit ears?
The TV rabbit ears are still around in some homes today although they are rapidly being replaced and thrown out. This is because now most people have either satellite or cable TV and these signals are distributed through a cable or a satellite digitally. Digital signals have gradually replaced the need for transmitting analog signals that rabbit ears can pick up. Before digital signals, cable and satellite dishes also contributed to the decline in rabbit ears.
Why does a tv with built in ntsc-atsc tuner do not pick up antenna signals?
On the settings or set up menu the tuner might not be set to receive off air signals or might be in the cable mode or it might be in the analog mode and you no longer have any analog stations to receive. Check to see if you are in the digital and antenna modes.

Is there a way I can get my satellite dish to pick up other signals?
You can make your satellite to pick up other signals by aligning the dish properly (elevation and azimuth alignment) taking into consideration the skew angle.
What is the purpose of the antenna on a radio and TV set?
Pick up the electromagnetic radiation (in the radio or TV bands) so that it can be brought into the set as electrical signals. This is analogous to the purpose of your eyes: pick up the electromagnetic radiation (visible light) so that the information can be brought into your brain as nerve impulses. However the antenna is usually just passive, whereas you eyes contain much of the active processing "circuits" that extract information that would be inside the radio or TV set.
What is a multi system plasma tv?
A multi system plasma TV is a TV that has a plasma screen. It is also able to pick up signals from various broadcasting systems. Other countries use PAL and SECAM, while America uses NSTC. For this reason, multi system TVs are compatible for use in many areas of the world.
