into digital signals through a process called analog-to-digital conversion. this involves sampling the sound wave regularly and measuring its amplitude, turning the continuous wave into a series of binary number
This is essentially what an acoustic levitator does, using sound moving through a gas in place of water. By placing a reflector the right distance away from a transducer, the acoustic levitator creates a standing wave. When the orientation of the wave is parallel to the pull of gravity, ...
On the other hand, identical waves that are in phase combine their compressions and rarefactions, doubling their amplitude. As sound waves travel, they spread out in all directions in a curved wavefront. The farther they travel from the source, the more they spread and the quieter the sound...
Make a signal which is 3 seconds long. The frequency is 50 Hz. The amplitude is 230 V rms (i.e. peak amplitude=325 V). The peak amplitude dips to 275 V for 1 second in the middle of the 3 second long signal.I

(See "How does a long-distance call work?" for a more detailed description.) Hand-generated! You know the hand crank on those old-fashioned telephones? It was used to generate the ring-signal AC wave and sound the bell at the other end! Telephones: Tones In a modern phone system, ...
How does QAM work? QAM is used to achieve greaterspectrum efficiency. This is accomplished by utilizing both the amplitude and phase components to modulate, or alter, the waveform. In this scenario, the QAM waveform consists of two signals, also known ascarrierwaves. ...
The large-amplitude nonlinear plasma wake wave driven by ultra-relativistic electron beams of different lengths and densities is studied using the analytical theory of the ultra-relativistic fluid equations. The approximate analytical solution for the wake wave is obtained and how to obtain large-...
Light sometimes acts as a wave and sometimes also acts as a particle or ray. The phenomenon of having these two characteristics is called the wave-particle duality of light. In the Answer and Explanation section, we will give two examples showing the evidence of such special traits....
The simplest form of a wave is a sine wave propagating along one dimension x in a time t, characterized by A(x,t)=A0sin(kx−ωt), where A can stand for displacement (wave on a string or on water), pressure (sound wave) etc. The characteristic parameters for the propag...
