Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...

Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves are ...

What Is A Periodic Wave? A periodic wave is a wave with a repeating continuous pattern which determines its wavelength and frequency. It is characterized by the amplitude, a period and a frequency.

Quarterly of Applied Mathematics, Vol. 68, No. 1 (March 2010), pp. 61-71 (11 pages) We address the problem of describing solutions of the nonlinear Schrödinger equation on a compact surface in the ...

The most important mechanical wave to our everyday lives is sound. So how exactly do we hear? What is the definition of sound? The Definition of Sound The first thing we should understand about sound ...

Wave speed is a measure of how quickly the wave travels from its source. Its value is the same as the distance covered by a wave in one second. Speed is measured in metres per second \(m\,s^{-1}\) and ...

Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
