The Dolby Digital reader shines an LED through this pattern as the film passes through the projector. The heightened sound quality of Dolby Stereo led moviemakers to make more extensive use of the surround channel. Today, Dolby Stereo is the analog sound standard, thanks to its superior sound quality and relatively simple installation. Dolby stereo also used an advanced noise-reduction process, which improved sound quality further. In addition to separating the different signals, proper surround decoders pass the audio information through different filters and noise-reduction elements to balance sound levels and reduce noise. Pro Logic decoders use active "steering" elements to control the process more precisely. The effect is that these out-of-phase signals move the electromagnet for the rear speaker, and so control the rear sound. In this surround-sound setup, the potentiometer simply acts as a volume control for the rear speakers. You can hook it up anywhere along the circuit leading to the rear speakers. With VoIP, you can make calls, even long-distance and international ones, for free.

Fre­e stuff is good, and free stuff that you'd ordinarily have to pay for is even better. Browsing the Internet at free hotspots can cut your television service bill, too, especially if you can use the connection to watch the shows you'd normally view on TV. But the e-brake is called an emergency brake for a reason -- using it can save your life. But National Weather Service forecasters are now using a technological advance that they hope will enable them to better predict where tornadoes are headed. If you hit the set button at 45 mph, the car will maintain your speed at 45 mph. Lots of home audio hobbyists have figured out a way to partially unlock the surround channel using only a two-channel home stereo and an extra set of speakers. The first set of planets engages the second set, and the second set turns the ring gear; this combination reverses the direction. The audio amplifier is constantly changing the direction of the current so that the orientation of the poles keeps switching. The particular sound produced depends on how rapidly and how far the cone moves, which is dictated by the fluctuation pattern in the electrical current.

Like Dolby Digital, SDDS encodes digital information with a distinct pattern of light and dark areas on film. The laser passes light through transparent areas of the film, but not through opaque areas. The photocells that are not exposed to light pass a small current on to the processor, but the exposed photocells do not. When you send an electrical current through the electromagnet, it becomes magnetized and acts like a natural magnet, with a north pole and a south pole. An audio signal, then, is just a fluctuating electrical current. The audio channels are encoded as magnetic tracks on video tape or broadcast as a television signal, rather than put down as optical tracks. If it's a mono-speaker television, it will play both stereo channels mixed together. If it's overinflated, you will ride on the center of the tread, and the tire will wear unevenly. The center signals on both streams are identical in amplitude and frequency, and they are synchronized exactly.

Also, most laptop CPUs are near the edge of the unit. The consequences might be more dire than, say, the processor on your laptop crapping out. These designs save space, but in some cases mean that the processor cannot be removed from the motherboard for replacement or upgrading. The CCD registers an image made of hundreds of little specks that represent 1s and hundreds of spaces between the specs that represent 0s. The Dolby Digital Processor unit interprets the digital information in this image as an audio signal. But the "same" and "difference" channels are a little more complex. The first two channels are fairly straightforward. Two of the most popular brands of these resistant all-in-one exercise systems on the market today are the Bowflex and Total Gym systems. In 1982, Dolby launched Dolby Surround®, a version of Dolby Stereo for home entertainment systems. In the next section, we'll take a look at these new digital theater sound systems. In later versions of the surround-sound system, theater owners could hook up a subwoofer to handle extremely low-frequency sounds (a crossover unit can separate out these sounds from both audio tracks). But instead of a single surround channel, it has separate channels for speakers on the left side of the theater and speakers on right side of the theater.
