Analog tv now uses mostly vhf-uhf frequencies for the standard network TV. UHF was added in the 60s for local urban TV signals with the addition of another tuner years ago. Any ham radio operator who has played with VHF 2 meters, or uhf , 450 mhz up, knows that UHF has significantly reduced range and is reduced to mostly line of site reception.
So guess what sports fans, rural users , with their shiny new converter boxes hooked up to vhf antennas are SCREWED!!! Unless you get an extended range UHF antenna , you will not get TV. You may not get digital TV either if you are too far from UHF digital transmission even with a new uhf "digital' antenna.
So, this whole thing is going to cause CHAOS to many rural and other users. Real good planning guys! Million of Americans will have no TV.....!!!!! Stay tuned for the fun on Feb 17, 2009!!@!!! The following is a update. Actually, there is no such thing as a digital antenna, all antennas are the same but a better antenna is one with a amplifier built in and mounted on the antenna itself. This helps the HDTV receive a stronger signal. An exception would be if you can see the transmitting tower from you location, no amplifier is needed. Always buy the VHF/UHF antenna with highest gain you can mount.

Who has a wide range digital or analog multimeter?
The analog multimeter has a wider range.
Why is radio better than tv?
One advantage of Radio over Television in this day and age is accessibility. Television broadcast has been limited to digital signals with a more limited broadcast range. Radio is still analog with a much larger, generally, broadcast range. Radio also tends to be less distracting to drivers...
Is frequency range of mobile communication is greater than FM?
There is no answer to this question, it needs to be reworded into a coherent form. Most mobile communications use F.M. (analog systems) or some form of digital transmission/reception.
What is necessary reason of digitization in place of analog cable system?
Without going into the fundamentals of analog and digital data transmission methods, a digital transmission can contain a higher amount of data than an analog transmission within the same frequency range. The change from analog TV to digital TV allows the content providers to have multiple TV stations per channel. Like say channel 13 use to have just the broadcast of one program in analog, but now there is more space, or bandwidth, to broadcast 3 or 4 programs on the same channel. 13.1, 13.2 and so on. Really the limit is how low of quality video the content provider wants to broadcast at. It's like changing the setting on youtube from 240p to 1080p. 240p loads faster than 1080p, but 1080p looks better.
Is the Sony Camcorder digital?
Sony has a wide range of camcorders, some digital some not. If you are looking for digital there are such ones as the HDR-TD10 or the HDR-P150V. If you are looking for analog then there is the CCD-TRV67 Hi-8 analog camcorder.
What is the radio frequency of TV?
Depends on the channel and whether analog or digital transmission. Analog channel-2 is the band 54-60 MHz. The video information is a single AM (upper) sideband about 4.2 MHz wide, with a small sniff of carrier transmitted at 54.25. The audio is on an FM carrier centered at 58.75 and deviated 25 KHz peak. (That's the layout for analog TV, which no longer exists. I have as yet no clue regarding the workings of digital TV.) All the rest of the 65 channels extend from here up to about 800 MHz. (Not all of this range is allocated to TV broadcast, but every TV broadcast channel is somewhere in this range.)
Is sound from a speaker digital or analog?
That would be analog. A speaker is not just on or off, and its range varies as the voltage changes. Sound cards use a D/A converter to convert digital data to audible sound.
What is digital and analog?
we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis)
What is analog device?
Analog devices are machines and components that react or work in a linear manner, often with an ability to make a continuous change. For example, a volume knob on a radio could be an analog device because it controls audio power output over a continuous range. Many amplifiers, power supplies, and radios use analog devices for generating or processing analog signals. Digital devices are machines and components that are always found in one specific state or another, rather than in some range between two points. Many analog and digital systems are designed to simulate the best features found in the other type of system, e.g., analog controls on a digital CD player, or digital controls on an analog radio.

Pulse Position modulation is digital or not?
Pulse position modulation can be analog or digital, it depends on the signal and/or the modulator used to obtain the modulation. If an analog signal is applied at the input of the modulator, the position of the pulse can assume an infinity of different timing states (the signal vary continuously) and hence an analog modulation is realised in PPM. On the contrary if the signal is digitized previously in a series of discrete states, the pulse at the output will have discrete timing interval (not continuosly). Then a digital modulation is obtained. If the signal is analog, but the modulator is digital, we will have again a number of finite state in output timing, and the PPM will be digital. To be noted that, if the number of steps in the digital modulator, is higher then the dinamic range required, the performance of the digital and analog PPM will be exactly the same. Cecking the front of the pulse of PPM with a digital oscilloscope capable of jitter measurament, we will see immediately if the position of the pulses will be continuosly variable or a number of discrete steps will be presented. We can then consider analog and digital PPM physically different.
