The amplitude value of a sinusoidal wave is calculated by operating means which processes absolute values of two data samples which are sampled from the sinusoidal wave at two points spaced 90 DEG electrical degrees apart thereby producing an electrical signal proportional to the amplitude value. The...

For a wave that is not changing, we can measure the amplitude from any peak or trough and measure the wavelength between any two successive points where the wave is in the same phase, as in the diagram below. We can read the wavelength and amplitude of a wave from a displacement–distanc...
Furthermore, dispersive behaviors are computed considering the effects of damping and rotation. The results demonstrate that flexural wave modes are very sensitive to the rotation effect. Particularly, in phase velocity spectra the characteristic frequency at the amplitude peak equals to the rotational ...
Figure 5: Excitation (red), sine (green), and cosine (blue) measured signals from a resolver. When viewed in detail (bottom) the signals are actually composed of amplitude modulated sinusoids, while the overall (top) signals appear as a sine, cosine, etc. ...
Dirac notation is used to represent quantum states as vectors in a Hilbert space. The notation consists of two parts: the "bra" ❴ or ⟨, which represents the dual vector or "ket" ❵ or ⟩, which represents the vector itself. These two parts are combined to form the "br...
Based on the assumption that the regular wave amplitude is small and researching object is Wigley ship model,a mathematical model of calculating diffraction wave pattern and pressure distribution caused by the moving ship in regular wave is established by using three-dimensional translating pulsating sou...

What is amplitude? Many Amplitudes − The sound field quantities of a plane wave Sound pressure level SPL and sound pressure "Sound level" is the sound pressure level in dB SPL or the sound intensity level in dB SIL. For Pa say, Pascal. This is the size for the pressure p = force ...
In this simulator the amplitude and phase of a light wave are represented by the amplitude and phase of an ac voltage. Each layer in the film is simulated by a four-terminal network containing adjustable attenuators and an adjustable phase shifter. The network obeys the same difference equation...
