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.

The second approach was modeling the sinusoidal function to analyze [[LAMBDA].sub.o] data.
Once a tentative model has been concluded, students focus on measuring necessary quantities that will constitute the form of the sinusoidal function. In order to further generalise the model, only one full cycle can be shown on the screen for the analysis.
Which component of the sinusoidal function should be changed to reflect this transformation?
This gives a sinusoidal function as a linear summation of the sinusoidal equations, each of which is deduced from the gravity-buoyancy and drag-gravity model, respectively.
By this realization, one sampled value of the sinusoidal function is generated within every VCO period and sent to the phase detector.
That resistor is turned on in the circuit within the period of time [DELTA]t and refers to the k - th sample of the discretized sinusoidal function. On this way, discrete values of the sinusoidal function are realized for a quarter of the half-period (0 - [pi]/2).
The changes of output flow rate with time (surging) were predicted for various time dependent input modes such as step function and sinusoidal function inputs into the hopper and other ports part way along the length of the machine, which could be useful for predicting the variations of the output product quality including the ingredients.
The road roughness and disturbances were simulated by step (representing uneven surface) and sinusoidal functions (representing pot holes and bumps) with 0.25 m amplitude and 0.5 sec of duration (Fig.
The higher order approximations include sinusoidal functions of additional multiples of the central or fundamental frequency.
