Are the harmonics in the SSVEP elicited by the fundamental stimulating frequency or by the artifacts of the stimuli? In this paper, we compare the SSVEP responses of three periodic stimuli: square wave (with different duty cycles), triangle wave, and sine wave to find an effective stimulus. ...

I have a sound wave representing a piano piece played at a steady tempo, and would like to get a graph of the saliency of each beat. I understand that this is done by plotting the autocorrelation function, however I don't quite understand why a graph of r coefficients against each po...
aThus the sine and cosine components at a particular frequency are expressed s a single cosine or sine wave together with a phase shift. If this procedure is applied to all harmonic components of the Fourier series, we get the alternative forms 因而正弦和余弦组分以一个特殊频率是表达的s一个唯...
Likewise, as the antenna “moves” away from the transmitter, the received frequency will decrease. By analyzing the sine wave representing this change in frequency, the direction finder can determine a bearing toward the transmitter. The RHOTHETA RT-500-M features a self-contained antenna uni...
Aiming at the amplitude modulated signal with frequency,a fast sinusoidal fitting algorithm for finding envelope is proposed. The algorithm is based on the least squares linear sinusoidal fitting method which does not need iterative operation. The forward recursive idea is used to fully utilize the ...
Parts of a Sine Wave There are various quantities used to analyze a sinusoidal function, including midline, amplitude, period, frequency, phase shift, and vertical shift. Midline The midline of a sinusoidal function is the horizontal line that divides the function exactly down its middle. In the...
(like Slack) so it makes sense to measure Daily Active Users (DAUs). But other products might look at Monthly Active Users (MAUs) instead. It’s not only the frequency that matters but also the definition of what ‘active’ means: if I’m a Slack user and only read messages but...
However, the frequency of the waves can affect the interference pattern that is created when the waves combine, which in turn can affect the amplitude at different points in space. Is the amplitude from superposition always equal to the sum of the individual amplitudes?
4.The range finding device according to claim 1, whereinthe light projecting unit and the image capturing unit use any one or a combination of amplitude modulation, phase modulation and frequency modulation as the intensity modulation of the irradiation light. ...
