sine wave

Sinusoidal waveform A waveform of periodic oscillations–eg, in alternating current in which the amplitude of each point in the wave is proportional to the sine of the time from a start point Cardiology An EKG finding described in severe hyperkalemia where the 'P' wave disappears and the QRS complex and 'T' wave merge in an oscillating pattern

sine wave

(sīn wāv)
A symmetric wave representing one complete cycle of a single-frequency oscillation; the displacement of mass over time described by using a function from trigonometry, the sine.

sine wave

continuous, oscillating stream of energy, generated by an electrosurgery unit; used during surgery to section/separate soft tissues (see Table 1)
Table 1: Forms of electrosurgery
Electrosurgery typeFeatures
ElectrofulgurationUses a high-voltage, dampened waveform to produce a spark that arcs from the probe tip to the skin lesion, causing superficial charring of the lesion surface
ElectrosectionUses an undampened or mildly damped current in conjunction with a very fine emitting electron to produce a cutting effect through soft tissue
ElectrocoagulationUses an intermittent damped current in conjunction with a larger emitting electrode to produce less intense heat over a larger area to induce coagulation and thereby haemostasis
ElectrodesiccationUses an intermittent damped waveform with high voltage and a lower current emitted from a ball electrode to induce cell dehydration and tissue shrinkage

The term that describes how a sine wave differential signal is affected by an interconnect when it exits is the differential insertion loss, sometimes referred to by its S-parameter designation, SDD21.
There is evidence the results may be somewhat different when sine waves at several frequencies are applied simultaneously, as happens in the real world.
The S-Parameters are a measure of the sine waves that scattered off the device, either reflecting back from the incident port or scattering into any other ports that might be connected.
Made of shock-absorbing Silastic(R) silicone rubber with threaded aluminum nuts/screws integrated into each end, Bumper Beans are designed for G-force sine waves between 80-250hz, reducing force by up to a factor of 10.
The Anabaria juvensis stromatolites, taken from the Bitter Springs formation in central Australia, snaked upward in the 850-million-year-old fossil record in the distinct pattern of sine waves.
is different from traditional narrowband wireless technologies that use sine waves and operate on a specific frequency.
Time Domain's Pulsed Ultra Wideband solution is radically different from traditional radio because it sends precisely timed pulses instead of traditional sine waves to communicate data and voice.
Using precisely timed pulses instead of traditional sine waves, PulsON sends millions of time-coded pulses across a wide swath of spectrum.
