  Amplitude - Wikipedia, the free encyclopedia
Amplitude is a nonnegative scalar measure of a wave's magnitude of oscillation, that is, magnitude of the maximum disturbance in the medium during one wave cycle.
The amplitude of sound waves and audio signals conventionally refers to the amplitude of the air pressure in the wave, but sometimes the amplitude of the displacement (movements of the air or the diaphragm of a speaker) is described.
The square of the amplitude is proportional to the intensity of the wave.

 Amplitude modulation - Wikipedia, the free encyclopedia
Amplitude modulation (AM) is a form of modulation in which the amplitude of a carrier wave is varied in direct proportion to that of a modulating signal.
Its output is a signal at the carrier frequency, with peaks that trace the amplitude of the unmodulated signal.
Forms of AM In its basic form, amplitude modulation produces a signal with power concentrated at the carrier frequency and in two adjacent sidebands.

 Energy Transport and the Amplitude of a Wave
As discussed earlier in Lesson 2, the amplitude of a wave refers to the maximum amount of displacement of a a particle on the medium from its rest position.
A tripling of the amplitude of a wave is indicative of a nine-fold increase in the amount of energy transported by the wave.
And a quadrupling of the amplitude of a wave is indicative of a 16-fold increase in the amount of energy transported by the wave.

 Amplitude for PlayStation 2 Review - PlayStation 2 Amplitude Review
Amplitude is about as bewildering to first-timers as Frequency was, though it does take several steps to alleviate the confusion.
Amplitude's multiplayer is generally better, partially because of the new track design, which allows all the players to see the action without resorting to a split screen.
There are also some significantly higher-profile tracks in Amplitude, including, but not limited to, tracks from blink-182, Pink, and Papa Roach and a remix of P.O.D.'s "Boom" by The Crystal Method.

Amplitude is a highly polished and undeniably cool music game and based on our early impressions, carries the series forward.

Amplitude includes streaming MPEG's of artist music videos, all new game arenas, since it is online there is a highly competitive online play mode, the game features a much more user-friendly interface and a more there is a diverse line up of genres and top artists.
Amplitude doesn't need a lot of graphical detail for the concept to work - it would still be a fun game (but not as entertaining) if it was fl and white like the Playstation Experience ads.
Amplitude has four different modes of play and a whole handful of levels to play on; working up from the easiest to the hardest levels and completing them takes a lot of time and practice.

 What is amplitude?
Amplitude is the objective measurement of the degree of change (positive or negative) in atmospheric pressure (the compression and rarefaction of air molecules) caused by sound waves.
Amplitude is almost always a comparative measurement, since at the lowest-amplitude end (silence), some air molecules are always in motion and at the highest end, the amount of compression and rarefaction though finite, is extreme.
In electronic circuits, amplitude may be increased by expanding the degree of change in an oscillating electrical current.

 amplitude. The Columbia Encyclopedia, Sixth Edition. 2001-05
In the harmonic motion of a pendulum, the amplitude of the swing is the greatest distance reached to either side of the central rest position.
Amplitude is important in the description of a wave phenomenon such as light or sound.
In general, the greater the amplitude of the wave, the more energy it transmits (e.g., a brighter light or a louder sound).

 DailyGame Review: Amplitude [PS2]
Sony has now released Amplitude, the sequel to Frequency, which, while it's not that much different from the original title, still is an amazingly good bit of fun.
Amplitude follows the nearly exact same gameplay model as the original Frequency.
While Amplitude is no longer a fresh idea (it is a sequel after all) and certainly is no graphical wonder, it's still an incredibly accessible title for every type of gamer, and is just a good time for anyone who picks it up.

 Amplitude (ps2: 2003): Reviews
Amplitude has blown the doors off its predecessor with more tunes and power-ups, better control, and crazy new background graphics.
The way that Amplitude is structured lends itself more to good reflexes, the memorization of patterns, and concentration rather than simply a good ear for music.
Amplitude has took the liberty in providing a difficulty about a notch above "expert" on frequency, so if you thought no one could touch you in that game, you need to realize that this "once virtually underground" game is attracting more and more players, meaning people are playing this a lot, especially online.

 Decibel Scales: Sound Pressure Level and Sound Intensity Level   (Site not responding. Last check: 2007-10-13)
Pressure amplitude is a measure of the size of the variation in air pressure caused by a sound wave.
For a pure tone--a pure sine wave--the averaging process leads to a pressure amplitude that is reduced from the maximum amplitude by a factor of 0.707 (equivalent to dividing by the square root of 2).
The relation between amplitude of the sine wave (measured from the background level to one extreme) to the pressure amplitude (average pressure excursion from the background) is shown in the figure below.

 GameSpy: Amplitude Review
But Amplitude (like Frequency) has an ungainly mishmash of rock, rap, and electronica that I can't imagine appealing to anyone, much less everyone, with B-sides from such wildly diverse artists as Korn, Weezer, Slipknot, blink 182, David Bowie, Papa Roach, Pink, and Garbage.
Amplitude's soundtrack was, to my personal tastes, about 40% hits and 60% misses, but you crazy kids with your ecstasy-fueled raves and your eight-sizes-too-big pants will probably record a much higher percentage.
Addressing the third issue: Amplitude, again like Frequency, allows you to create an avatar called a "FreQ." In the first game, the avatar was a 2D sprite, but here, it's a 3D construct, pieced together from a menu of unlockable heads, torsos, arms, legs, gear, and emblems.

 Amplitude (Playstation 2) Review at RewiredMind.com   (Site not responding. Last check: 2007-10-13)
Amplitude, the sequel to Sony’s 2002 sleeper hit Frequency, takes you into a world of tubes, flashing lights and some very trippy dreams.
Amplitude however, features a flat playing field, meaning that once you’ve gone as far left as you can go, that track on the far right is always going to be 7 or so steps away, which will doubtless call for some rapid-fire button hammering if you’re going to keep your song pumping.
Amplitude is one of the few that are actually any good.

 Agilent Technologies | Educator's Corner - Resource Guide for Engineering Educators | Amplitude Modulation
Amplitude modulation was the original method used for transmitting audio signals over radio frequency waves.
In an AM signal, the idea is to modulate the carrier waveform without changing phase - only the amplitude is supposed to change.
that leads us to the model of a single carrier and two oppositely-rotating vectors that sum to change the amplitude of the carrier, but not its phase.
