Analog signals are recorded in their original form, for example, recording to a tape. Analog signals can be read and amplified, but can also be damaged by the environment, and degraded with ancillary equipment which reduces sound quality. Digital signals are recorded in binary code (numbers that consist of only 0 and 1) and reproduce at the source, and this is one reason the signal can't be damaged or degraded.

Yes, VPR's HD radio stations will broadcast both digital and traditional analog signals. Because new HD Radio stations will begin their digital broadcasting using a "hybrid mode" (transmitting digital and analog signals simultaneously), you'll still be able to pick up our broadcasts on your analog radios. The stations will seamlessly upgrade to digital when it locks onto a strong digital signal. See similar questions...

The current Edifier model S2.1D accepts digital input for front speakers and rear speakers. The other models in current production accept analogue inputs. See similar questions...

Analog phones operate on an older and less effective technology. This technology doesn't scale well and is more costly. Analog service is not compatible with numerous new features. Digital phones are lighter and more compact and have a longer battery life. When you are inside of a calling area the quality is better than analog. Digital phones support new features like caller ID, text messaging or wireless internet services. See similar questions...

A digital cordless phone converts your conversation into 1's and 0's when transmitting back to the base unit. This provides better security, but analog transmissions may have better sound quality since they do not go through a conversion process. See similar questions...

When cellular phones first started being used, about 20 years decades ago, analog was the only available network technology. Today, PCS refers to digital technology. With Digital technology benefits are that data and bandwidth can be increased. See similar questions...

Analog phone service was the original form of cellular service. The problem with analog cellular is that it is not a highly secure transmission method and is not efficient for use with a large number of users. Digital cellular makes much better use of the available airwaves and is more secure for transmitting voice messages. In order to take advantage of the benefits of digital cellular a special digital phone is required. See similar questions...

Analog: Standard picture and sound quality with up to 80 channels. Digital: DVD picture and sound quality with more than 300 channels. HDTV: 10 times better resolution/image detail than analog with up to 3 channels currently available; more channels will be added in early 2004. See similar questions...

Digital is a quicker braking reaction than an analog. With digital reaction time is1/4 to 1/2 of a second, analog takes 2 to 3 seconds. See similar questions...

Analog is yesterday's technology. Virtually everything that has electronics utilizes computer technology today is digital. The Masterpiece/Marvello uses state of the art MICOM Technology to implement the entire ionization process. That way nothing is left to chance and the proof is in the water: The ionization levels provide a pH of 8.5-10+ Alkaline, and 6.5-5.5 Acidic. (Keep in mind that over-ionized water with a pH 10+ does not taste good. See similar questions...

Analog technologies modulate radio signals without compressing data. This is the most inefficient and therefore most expensive mode of transmission. Digital technologies, on the other hand, convert speech into a sequence of binary symbols over a narrow range of frequencies. A similar battery will last longer with a digital phone as compared to an analog phone. Yes, however if you are not in an area with proper reception, your call may not go through. Currently the F.C.C. See similar questions...

a) There are thousands of frequencies between each positioned frequency on a digital machine that are missed when going from one frequency to the other. This means that when you set the dial to a specific frequency like 800 then move up the scale between 800 (800.0000) and 801 (800.9999). There are thousands of combinations of frequencies (resonant and harmonic) surrounding the target frequencies that are covered when using an analog machine. See similar questions...

Digital and analog refer to two methods of controlling the position of spinning gyroscope rotors inside their housings. The Gyroscope Suspension System applies tiny, precise electromagnetic potential changes as needed inside each rotor housing. There are three electrodes on each housing half (six total per complete housing) that monitor and then control the electrostatic suspension of the GP-B gyros. You can learn more about the gyroscope hardware in our educational lithograph. See similar questions...

a technology, analog is the process of taking an audio or video signal (in most cases, 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. See similar questions...

Analog mammography uses x-ray to record images on film using an x-ray cassette. Films are then "developed" and produced and put on a light box and read by the Radiologist. With Digital mammography the x-rays produce a digital image on a screen while the patient is still in position. The technologist has the ability to review these in "real time" to determine image quality. See similar questions...
