Difference Between Analog and Digital?

Analog and Digital
As a technology, analog is the process of taking an audio or video signal (the human voice) and translating it into electronic pulses. Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s. Simple enough when it's the device—analog or digital phone, fax, modem, or likewise—that does all the converting for you.

Digital versus analog can refer to method of input, data storage and transfer, the internal working of an instrument, and the kind of display. The word comes from the same source as the word digit and digitus.The digital technology breaks your voice (or television) signal into binary code a series of 1s and 0s transfers it to the other end where another device (phone, modem or TV) takes all the numbers and reassembles them into the original signal. The beauty of digital is that it knows what it should be when it reaches the end of the transmission. That way, it can correct any errors that may have occurred in the data transfer. What does all that mean to you? Clarity. In most cases, you'll get distortion-free conversations and clearer TV pictures. The nature of digital technology allows it to cram lots of those 1s and 0s together into the same space an analog signal uses. Like your button-rich phone at work or your 200-plus digital cable service, that means more features can be crammed into the digital signal. Digital offers better clarity, but analog gives you richer quality. Digital like the VCR or the CD is coming down in cost and coming out in everything from cell phones to satellite dishes.

Phone lines

• Digital lines are found in large, corporate phone systems. Though digital lines carry lower voltages than analog lines, they still pose a threat to your analog equipment.
  
• Analog lines also referred to as POTS (Plain Old Telephone Service), support standard phones, fax machines, and modems. These are the lines typically found in your home or small office
  
• There are digital-to-analog adapters that not only let you use analog equipment in a digital environment, but also safeguard against frying the internal circuitry of your phone, fax, modem, or laptop.

Cordless phone

The very nature of digital technology—breaking a signal into binary code and recreating it on the receiving end—gives you clear, distortion-free cordless calls.

Cordless phones with digital technology are also able to encrypt all those 1s and 0s during transmission so your conversation is safe from eavesdroppers. Plus, more power can be applied to digital signals and thus, you'll enjoy longer range on your cordless phone conversations.

The advantage to analog cordless products? Well, they're a bit cheaper. And the sound quality is richer. So unless you need digital security, why not save a few bucks and go with an analog phone? After all, in home or small office environments where you may be the only cordless user, you won't have any interference issues.

when talking about digital and analog cordless phones, you're talking about the signals being transferred between the handset and its base. The phones themselves are still analog devices that can only be used on analog lines. Also, the range of your cordless phone—analog or digital—will always depend on the environment.

Cellular Phones

• Perhaps the most effective use of the digital versus analog technology is in the booming cellular market. With new phone activations increasing exponentially, the limits of analog are quickly being realized.
  
• Digital cellular lets significantly more people use their phones within a single coverage area. More data can be sent and received simultaneously by each phone user. Plus, transmissions are more resistant to static and signal fading. And with the all-in-one phones out now—phone, pager, voice mail, internet access—digital phones offer more features than their analog predecessors.
  
• Analog's sound quality is still superior—as some users with dual-transmission phones will manually switch to analog for better sound when they're not concerned with a crowded coverage area—but digital is quickly becoming the norm in the cellular market.

Better Sound Quality
Digital offers a better quality of sound. Proponents of digital claimed too that because digital scrambled up the signals into bursts, it was more secure than analog and can help thwart "cloning," an act of grabbing phone account information over the air in order to copy then resell that information for piracy purposes. By some industry estimates, close to $650 million in wireless services has been coveted by these big-eared crooks, which only adds onto the operator's bottom line a cost that is eventually passed on to the customer. Digital has stronger battery life than analog, and for the most part, better, more modern features on the phones.

Buying a Television

Television is a telecommunication system for broadcasting and receiving moving pictures and sound over a distance. The term has come to refer to all the aspects of television from the television set to the programming and transmission.

The elements of a simple television system are:

• An image source - this may be a camera for live pick-up of images or a flying spot scanner for transmission of films
• A sound source
• A transmitter, which modulates one or more television signals with both picture and sound information for transmission.
• A receiver (television) which recovers the picture and sound signals from the television broadcast.
• A display device, which turns the electrical signals into visible light.
• A sound device , which turns electrical signals into sound waves to go along with the picture.

Display technology
Thanks to advances in display technology, there are now several kinds of video displays used in modern TV sets:

• CRT: The most common displays are direct-view CRTs for up to 40 in (100 cm) (in 4:3) and 46 in (115 cm) (in 16:9) diagonally. These are still the least expensive, and are a refined technology that can still provide the best overall picture quality. As they do not have a fixed native resolution, in some cases they are also capable of displaying sources with a variety of different resolutions at the best possible image quality. The frame rate or refresh rate of a typical NTSC format CRT TV is 60 Hz, and for the PAL format, it is 50 Hz. A typical NTSC broadcast signal's visible portion has an equivalent resolution of about 640x480 pixels. It actually could be slightly higher than that, but the Vertical Blanking Interval, or VBI, allows other signals to be carried along with the broadcast.

Cutaway rendering of a color CRT

• Electron guns
• Electron beams
• Focusing coils
• Deflection coils
• Anode connection
• Mask for separating beams for red, green, and blue part of displayed image
• Phosphor layer with red, green, and blue zones
• Close-up of the phosphor-coated inner side of the screen

Rear projection: Most very large screen TVs (up to over 100 inch (254 cm)) use projection technology. Three types of projection systems are used in projection TVs: CRT-based, LCD-based, and DLP (reflective micromirror chip) -based. Projection television has been commercially available since the 1970s, but at that time could not match the image sharpness of the CRT; current models are vastly improved, and offer a cost-effective large-screen display. A variation is a video projector, using similar technology, which projects onto a screen.

Flat panel LCD or plasma: Modern advances have brought flat panels to TV that use active matrix LCD or plasma display technology. Flat panel LCDs and plasma displays are as little as 1 inch thick and can be hung on a wall like a picture or put over a pedestal. Some models can also be used as computer monitors.

Buying Tips & Suggestions
If you are shopping for a new television, there are many things to consider before buying. Viewing habits, size of unit, size of screen, price, brand, style, type, and quality are all important issues. Don’t forget to find out about the cost and time required for delivery if you are unable to retrieve the TV yourself.

When it comes to size, you need to determine not only the size of the room in which the TV will be placed, but also the size of the stand, entertainment center, or other unit that will house the television. Don’t forget to bring a tape measure with you to the store so you can measure the TV you want to buy and make sure it will fit inside the unit. You need a little extra space around the television to allow airflow, to clean the TV, and to hook up other components.

When it comes to getting your new TV home, make sure the one you chose will fit inside your vehicle. Also, ask for help placing the television into your vehicle instead of struggling to maneuver it yourself. Make sure you have help available to bring the set in from your car once you arrive at home as well. Some shops offer free delivery if you spend a certain amount or buy a certain size TV or larger. In this case, you should take advantage of delivery, not only because it is more convenient, but also because the seller bears all the responsibility for the set until it is safely placed inside your home.

When choosing a TV, pay special attention to picture quality. The darker the screen when the set is turned off, the crisper the picture will be, because the TV can provide greater contrast than those with lighter screens, such as those that appear light gray or green. Also important is the curvature of the picture tube. Flat screens are preferred, because images are viewed in clean lines rather than curved lines, and there is far less glare from other light sources with a flat screen TV.
