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.

An analog signal is one that continuously varies up and down in amplitude while a digital signal is a signal that is either on or off. Typically cross pinned products are used for Telephony, and straight pinned products are used primarily in Data applications.

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.

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

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.

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.

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.

Analog: The National Television Standards Council (NTSC) standard TV format (channel 3 output). This format is based on a video picture of 525 horizontal lines scanned from left to right across the television picture tube starting at the top of the screen (interlaced video). Digital: Digital Video Compression (DVC) allows us to compress more channels into a much smaller space than analog transmission allows.

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.

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.

The term Digital refers to the means by which two electronic devices communicate to each other (transmitter/receiver in computers, radios, CD Players, etc). Digital is the use of computer codes comprising of just two signals. The first one is on signals (a 1 signal) and the second is an off signal (a 0 signal). This means of communication is one of the most efficient means of transferring data. This series of ons and offs, when written look something like this: 011000101110111.

Digital TV has the digital Set Top Box that allows you to get Pay Per View, digital music stations, as well as access to many more channels and the ability to order PPV. Local channels are available for an additional fee. Analog does not require any equipment thus no extra wires or power cords. Just plug your TV into the wall and you are off and running. Local channels are included within the analog plan.

Quality, time, and flexibility. It is that simple. Digital video has a higher level of quality than the best S-VHS. Digital editing is considerably faster than editing analog video. And finally, video "sweetening" is possible that was either too expensive or impossible to do in the analog video world. (i.e. color-correction of the video, slow motion effects, changing segments to black and white, and other special effects as appropriate).

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.

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.

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.

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.
