Sine Wave

Any curve plotted along an axis where the y-value moves above and below zero at a rate of y = sin(x). The Composite Index of Lagging Indicators is thought to be roughly a sine wave because interest rates and inflation, which make up the index, move in relation to each other in a way resembling the sine.

The difference between using only a sinusoidal wave and several harmonics looks subtle, but the result is remarkable.
In most cases it is assumed that the electrical current and voltage have a sinusoidal wave shape.
Because of difficulties in precisely evaluating the absolute sensitivity in the frequency range of several tens of kHz, we inputted a sinusoidal wave from a PZT transmitter to a thin (t = ~20 mm) rock specimen and observed the output.
Using a 386 computer, operators program the requisite carriage parameters for their study, such as constant speed, sinusoidal wave pattern, or elliptical orbits.
The brushless d-c stator runs on a trapezoid waveform, while the a-c stator is designed to run on a sinusoidal wave current.
included in her studies characteristics like "waveshape" (varying from the pure tone of a sinusoidal wave to the ragged buzz of random fluctuations) and loudness.
if, as part of the command strategy, the sinusoidal reference wave is replaced by a modified sinusoidal wave (discontinuous command techniques DPWM) [7], described in (5)
Look-in table and the D/A converter are replaced by the generator in which n samples of the sinusoidal wave form are generated.
The DFS is built on the proven platform of the Resolute Integrity(TM) DES with Continuous Sinusoid Technology (a unique Medtronic method of stent manufacturing that forms one single strand of wire into a sinusoidal wave enabling a continuous range of motion), as well as the next-generation Resolute Onyx(TM) DES with CoreWire Technology that allows it to have a denser core metal surrounded by a cobalt alloy outer layer for thinner struts with enhanced radiopacity (visibility during imaging).
