One can assume that the statistical errors are constant from measurement to measurement, and do a least-squares fit to the data of a linear function modulated by a sinusoid. From Wordnik.com. [“The Entire Planet!”] Reference

If some other signal – say 1/90 year signal – exists in the reconstruction, the response in the DFT will be the convolution of the section of signal zero padded in either direction to infinity with a sinusoid at each frequency in the DFT. From Wordnik.com. [Ammann at AGU: the Answer « Climate Audit] Reference

For instance, let's consider the sine wave, or sinusoid, a mathematical function that describes a smooth repetitive oscillation. From Wordnik.com. [Efímera] Reference
So it needs two variables: the "x", which linearily goes from 0 to 100, and "y", which is a sinusoid function that goes from -1 to 1. From Wordnik.com. [The Code Project Latest Articles] Reference
The phase of the sinusoid at each point was used to modulate the color of the pixels along the hue axis in the HSV color space, as shown in figure 1a. From Wordnik.com. [PLoS ONE Alerts: New Articles] Reference
Either way, a min / max can only be a suitable sample if the signal is a pure sinusoid, or some other time symmetrical waveform; which is most unlikely. From Wordnik.com. [WordPress.com News] Reference
For real-time performance, we need to pretabulate the sinusoid values to perform the smallest number of calculations possible, preferably working on integers only. From Wordnik.com. [Recently Uploaded Slideshows] Reference
In summary, we suggest that immature-B cell movement from parenchyma into sinusoid is promoted by S1P1-signaling within the B cell in response to the higher S1P concentration within the sinusoid. From Wordnik.com. [PLoS ONE Alerts: New Articles] Reference
Certainly, the rule of twelfths is a good enough approximation to predict the height of a tide tidal curves, but it assumes a sinusoid tide that when plotted on a diagram shows a smooth repetitive oscillation. From Wordnik.com. [On Kayaks] Reference
