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.

Given a signal r(t) based on a sinusoidal waveform, with the formula shown in (2), it is necessary to obtain a synthetic signal r (t) that minimizes the error.
where [[DELTA].sub.d] is the distance between arbitrary adjacent discrete samples on the x'-axis and Aml is the tracking amplitude of the sinusoidal waveform which is divided into n parts along the x'-axis.
The objective of this paper is to propose two methods for predicting the frequency of tensile stress and strain pulses at the bottom of asphalt layer in both longitudinal and transverse directions based on haversine and sinusoidal waveforms. By applying these methods, the frequency of loading in HMA fatigue laboratory tests such as four-points bending beam and indirect tensile (IDT) fatigue tests can be determined more realistically based on pavement design and loading characteristics.
For that reason, if you reshuffle the sampled sinusoidal data according to the primary phase order, it can be reconstructed to a single cycle sinusoidal waveform, an operation called coherent waveform reconstruction.
As a result of tests, a very low level of ripple torque as well as almost sinusoidal waveform and predicted level of line voltage were achieved.
Simultaneously, the pulse oximetry waveform changed from a sinusoidal waveform to a more complex trace, with characteristics similar to that seen in a venous waveform (Figures 1 and 2).
This frequency converter incorporates high frequency PWM technology to synthesize a regulated sinusoidal waveform with less than 5 percent total harmonic distortion.
The most evident way to generate this driving voltage from a sinusoidal waveform is by using a nonlinear circuit.
In an EIS experiment a sinusoidal waveform of small amplitude is applied to the specimen.
The velocity matches obtained in Experiment 1 indicate that the sinusoidal waveform produced significantly better performance for both accuracy and latency than the stair-step waveform.
The summation of two concurrent multiharmonic signals, such as hums that differ in their F0s, results in a complex sinusoidal waveform with multiple envelope periodicities at difference frequencies (dF) between (1) the F0s of each signal; (2) their higher harmonics; and (3) the F0s and higher harmonics.
They also concluded that a pulse waveform better corresponded to tire results as compared to a sinusoidal waveform especially in a sidewalk deflection.
