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 1 kHz sine wave signal provided for the best overall results of the restoration processes.
1 kHz files usually provided improved correlation values, except for the 1 kHz sine wave signal.
025 kHz/16-bit multiple sine wave signals, clipped to +12 dB, and restored using program #1.
025 kHz/16-bit multiple sine wave signal; the restorations were applied after the file was clipped to +12 dB.
When a sine wave goes into Port 1, it can do a number of things.
With four ports, there are 16 possible combinations (FIGURE 4) of sine wave going ins and coming outs.
In addition to the number of days in a year, the sine wave pattern of the ancient stromatolites contains information about another important astronomical parameter called the obliquity of the ecliptic, or the angle between the planes of the earth's equator and the planet's orbit around the sun.
