Frequently Asked Questions

What is the difference between digital and analog signals for speakers?

Lowyat.NET -> FAQ for Edifier Speakers
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.

What's the difference between analog and digital phones?

Cell Phone Numbers - Cell Phone FAQ
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.

What is the difference between Analog and Digital?

Welcome to www.vtech.com
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.

What is the difference between Analog and Digital or PCS?

Just Pennies
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.

What is the difference between Analog and Digital service?

The Wireless Warehouse : FAQ
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.

What is the difference between analog, digital and HDTV?

Grande Communications - FAQs ; How-Tos
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.

What is the difference between digital and analog?

Towing World Official Website
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.

What is the difference between analog and digital technologies?

Frequently Asked 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.

What is the difference between analog and digital cassette files?

FAQ - Frequently Asked Questions - Audio Notes Recorder
quot; Conversion to MP3 is not possible because MP3 codec installed on this computer does not support requested sound quality parameters. Lower the quality and try again"

Is the Toyo Analog or Digital and what is the difference between these two?

Alkaline Ionized Water - Toyo Mavello Water Purifler Water I...
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.

What is the difference between analog and digital machines?

Original Style Rife Equipment
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.

What is digital and analog suspension? What is the difference?

Frequently Asked Questions about Gravity Probe B
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.

What is the difference between Analog and Digital Phone lines?

Phone and Dataline Surge Suppression: Frequently Asked Quest...
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.

What is the difference between traditional (analog) and Digital Mammography?

Norwalk Radiology & Mammography Center: Digital Mammogra...
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.

Why is the transition from analog to digital television happening?

NTIA: Digital TV Transition and Public Safety
Because digital broadcasting is more efficient than the current "analog" technology, less of the airwaves are needed to provide programming to consumers. The unused spectrum which broadcasters no longer require will be used for two important purposes. First, it will be given to first responders - our nation's firefighters and police - to better communicate with each other during emergencies.

What is the difference between analog and digital hearing aids?

CHIP - Communicaid for Hearing Impaired Persons
In basic terms, an analog is like an ordinary amplifier in that it amplifies all sounds around you whether it is conversation or background noise. Digital hearing aids have the ability to control background noise, feedback, and enhance certain frequencies if necessary. The sound quality can be much better than analog hearing aids. Most manufacturers today produce only digital models and analogs are being phased out.
