Caption: Figure 4: (a) Left panel shows multifrequency sinusoidal wave
with 500 sample points; middle panel shows the MSE for various length time series across several scaling factors; right panel shows normalized MSE (for scale factors [tau] = 1-10) and SE; (b) top row shows sinusoidal wave
with white noise, (c) pink noise, and (d) brown noise; (b) bottom row shows normalized MSE (for scale factors [tau] = 1- 10) and SE for sinusoidal wave
with white noise, (c) pink noise, and (d) brown noise, respectively.
As the "triangular wave" is fitted as above, it can be comprehended by analogy that any periodic wave can be reconstructed by the "sinusoid fitting" algorithm based on the HHT; in other words, any original "periodic wave" can be characterized as the "sinusoidal wave
" whose amplitude and phase are both transient.
Previously, we evaluated the detectability using a synthetic wave signal consisting of sinusoidal waves
and random noise and showed that the arrival times of linearly and elliptically polarized signals can be detected within 10 sampling points at a signal-to-noise ratio (S/N) of -7 dB .
Current waveform should be pure sinusoidal wave
. But according to network harmonics and internal motor faults, harmonics are imposed on the current.
For electricity production, consider a sinusoidal wave
approaching a mid-Atlantic U.S.
At the output end of the full bridge inverter we get a squared wave output voltage waveform rather than getting a sinusoidal wave
. Hence we use filter to get pure sinusoidal output voltage.
The sinusoidal wave
is created digitally using a numerically controlled oscillator (NCO).
Seasonal patterns were modeled using sinusoidal wave
The action of an assumed sinusoidal wave
motion impending on the side of a ship can be considered a driving force of adjustable frequency and amplitude.
The Fourier hypothesis predicts lower perceived velocities (relative to consistent directions) and a lower rate of perceived velocities for the sinusoidal wave
form than for the stair-step waveform (dashed lines and circle symbols).
Working with services engineer Max Fordham & Partners, the concrete upper floors are of sinusoidal wave
form sections to maximize the surface area of the ceiling, allowing the thermal mass of the concrete to temper the environment.
