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.

Currently the standard test procedure is to measure the stiffness for sine wave input at a regular series of frequencies, for example every 10 hz from 0 hz to 200 hz.
The solution is to borrow an approach used in the RF world: that is, to use the interactions of precision sine wave signals with the connector to characterize its performance.
If a sine wave enters a port, there are only three qualities of it that can change when it comes out again; its frequency, amplitude or phase could be affected.
They did this by looking at paleomagnetic studies of the rocks to determine the direction of the past field, and by using the plane along which the stromatolitic sine waves grew to define the past north-south plane of the earth and its spin axis.
While traditional wireless technology uses sine waves and operates in a specific frequency, Time Domain's PulsON technology sends millions of low power pulses per second across a wide spectrum.
Fullerton's method is different from current wireless communication because it transmits audio, video and other data in precisely timed pulses, instead of the traditional continuous sine waves.
Users can also map a video channel to geometric shapes, such as spheres, sine waves and raindrops.
This interference results in a very accurate sine wave signal with a pitch that is 1/4 times the scale pitch.
