Generally speaking, when you have the choice between toslink (optical) and digital coax, the digital coax sounds better. Both carry a digital signal, but the optical signal goes through 2 extra conversions (electrical->light and light->electrical). The optical connection has shown to have more jitter problems.

Technically, a coax connection will sound better because there is less processing to the signal. In certain situations, when experiencing EMI, RFI or long distance cable runs, using an Optical cable would be your best choice.

Coax is a standard cable that connects your tv and or cable modem to your wall outlet. Generaly the wiring for tv/broadband is done in coax cabeling called RG-6. The cable has a copper core surounded by a plastic sheathing, this is surounded by a braided outer cover of woven mesh wire and in turn is covered by an outer sheath. First, you need to provision your account (additional $5 per/mo.) for two computers. Contact HarborNet for this. Or you can purchase a small office router.

Agilent and NSI coax mixers can be used up to 50 GHz, and are typically preferred over the waveguide mixers due to their lower cost and convenience of having a broadband device (typicallly 1 - 50 GHz). Agilent's waveguide mixers have been discontinued; these used fairly high harmonic numbers resulting in high conversion losses. Above 50 GHz, waveguide mixers are the only solution.

First, we need to think clearly about what it means to be a good photographer. This entails having the artistic sense to understand and create good compositions, the equipment to capture the image, and the know-how to control the equipment properly. Simply purchasing a digtal camera will not impove your composition skills or increase your know-how. However, there are at least three ways that digital camera technology can help you: It can help you learn faster.

It's important to understand this difference, as you could be disappointed with the results if you use one rather than the other. Optical zoom works like the zoom on a traditional film camera. When you push the button to zoom in or out, physical lens elements move inside the camera, reducing the field of view and making the object you're shooting appear closer. Digital zoom, on the other hand, has no moving parts.

The optical keystone angle is the angle between the optical axis and the center of the projected image. This varies by some degrees and is dependent of the position of the zoom lens. This angle is actually a fixed angle and can only be "changed" by turning the zoom lens Digital keystoning gives you the possibility to have a correct square image, even when the image is thrown upwards in desktop mode or downwards in ceiling mode.

Yes. The specifications for composite video, component video and digital coaxial cables are EXACTLY the same! Since our PSC cable maintain a 75-ohm impedance from tip-to-tip, it is the perfect cable for each of these connections. For component video applications you will need three PSC cables (which we offer on our website in special component cable discount packages).

Recent studies indicate a higher cancer detection rate of digital mammography in certain patients, including those with dense breasts, those under 50 years old, and those who are pre- or peri-menopausal.

These two terms refer to a picture's resolution. Optical zoom increases magnification while maintaining image quality as it moves the lens to zoom in on a subject. Optical zoom is the maximum resolution that the camera can capture. It uses lens movement to focus on distant subjects, but the range is limited. It produces enlargements without color or focus degradation.

The optical zoom is 7.8 ~ 39 mm (37.5 mm ~ 187.5 mm when converted for 35 mm film), which corresponds to a zoom ratio of 5. The digital zoom provides a zoom ratio of 4, so both in combination provide a maximum zoom ratio of 20.

Optical zoom is achieved by changing the focal distance of the lens, so there is no loss of image quality. Zoom adjustment is step-less, up to 3X. With digital zoom, the center of the image is extracted and shown on the display. You can toggle digital zoom between 2X and 4X. Recording a 800 x 600-pixel image using 2X digital zoom display data from each CCD pixel as-is, so there is no change in image quality or magnification.

It's important to understand this difference, as you could end up mighty disappointed with the results if you get one...

Yes, the AVX does come with optical digital out (toslink), as well as RCA digital out, and 6 channel Analog out.

Unlike optical measurement systems, the accuracy of capacitive measuring systems is not affected by sawdust or other non-conductive contaminants. Additionally, power consumption is much less than optical measurement systems, which enables ProScale to operate on standard batteries for many months (and makes installation much easier). Also, ProScale is a solid-state electronic device, so there's very little to wear out.

Optical soundtracks (we mentioned them earlier). Almost all of the release formats, including the digital ones have provision for some kind of optical soundtrack, even if only as a backup. The optical soundtrack refers to the two-channel soundtrack that is carried on the optical track of the film release print.

Once your surround sound format has been selected (see the paragraph below for more), you need to order an optical soundtrack negative for the film. In the case of LCRS mixes, a traditional two-channel; Printmaster track is created, and this is sent to an optical sound house for the creation of the optical negative. The optical sound house will record the soundtrack onto 35mm film using a special camera, and some will also develop their own soundtrack masters.

Ultera's Optical RAID controller solutions virtualize an array of optical devices using RAID (Redundant Array of Independent Devices) to operate as a single logical optical drive. Seen by the host as a single optical drive with increased performance, online storage capacity & reliability. Optical Striping (RAID Level 0) increases performance and online storage capacity up to 4 times more than a single optical drive.

A coaxial digital audio cable uses copper wiring as its signal conductor and dual-RCA jacks as connectors. An optical digital audio cable uses fiber optic wiring as its conductor and dual Toslink connectors. Both types of cables perform the same function; however, an optical digital audio cable is immune to external interference because its conductor is non-metallic.

You cannot use the optical zoom while recording in Moving Picture mode. Digital zoom is possible when recording movies.

No. However, there are aftermarket products that convert the coaxial type of digital audio output to the optical type.

A3: Optical zoom is the traditional method of physically manipulating the distance between 2 lenses to create a different camera view. Digital zooming is a technique in which an electronic processor literally magnifies size of the pixels imaged by an optical lens. There are different techniques, but "grainy" appearance is typically associated with digital zoom, especially when the camera.

If optical zoom is used alone or when 2X digital zoom is used, image sizes are the same as normal: 1600 x 1200 pixels, or 800 x 600 pixels. When 4X digital zoom is used, however, image size is always 800 x 600 pixels.
