## Sine wave

A wave having a form which, if plotted, would be the same as that of a trigonometric sine or cosine function. The sine wave may be thought of as the projection on a plane of the path of a point moving around a circle at uniform speed. It is characteristic of one-dimensional vibrations and one-dimensional waves having no dissipation. See Harmonic motion

The sine wave is the basic function employed in harmonic analysis. It can be shown that any complex motion in a one-dimensional system can be described as the superposition of sine waves having certain amplitude and phase relationships. The technique for determining these relationships is known as Fourier analysis. See Wave equation, Wave motion

(physics)
A wave whose amplitude varies as the sine of a linear function of time. Also known as sinusoidal wave.

## sine wave

A wave form containing only one frequency; the amplitude of the periodic oscillation is a sinusoidal function of time. Also see pure tone.

(Total impedance of the source region is equal to the characteristic impedance of the feedline (50 [ohms]).) The source is applied five meshes inside the feedline in the propagation direction and the values of the electric fields are calculated during the sixth period of the sinusoidal waveform to avoid the transition-period effect.
To assess the linear range of ampullary responses, we used spectral analysis to determine the amplitude of harmonics generated in the trans-ampullary current in response to trans-organ voltage clamps to a 0.5-Hz sinusoidal waveform. Preparations gave linear responses (Fig.
