(electronics)
Sampling in which the individual samples are of such long duration that the frequency response of the channel is not deteriorated by the sampling process.

where i is the searched ith boundary point, j is the jth discrete sample point in a sinusoidal waveform cycle, [s.sub.ij] is the z-position of the jth discrete sampling point in the ith sinusoidal waveform, and [Ps.sub.ij] is the z-position of the probe which represents the surface topography.
The discrete sampling of the channel frequency response in different systems can be obtained by different methods.
However, the discrete sampling given in Figure 9(a) and the finite length of the sampling series cause the convolution (51) to take the only possible peaks in the spectrum at f = {-2,2}, because all other 2[pi]-periodic values multiplied with the sampling kernel (sinc-function) evaluate to exactly zero.
The light source-cuvette holder can be removed; spectrometer entrance slits can be switched out to adjust the resolution and throughput; and discrete sampling devices can be used in place of the direct-attach accessories.
Based on these purposes and the required accuracy, an appropriate sampling method can be selected from different sample collection methods (grab sampling, discrete sampling, composite sampling, combination of discrete and composite sampling, combination of grab and composite sampling, etc.), which are illustrated in the section 'Results and discussion'.
He presents the results of four tests on equity, bond, commodity, and currency exchange-traded funds, and looks at models of return auto-correlation, and the discrete sampling of variances.
POCIS sampling provides a time-weighted average of chemical exposure over several weeks, whereas discrete sampling provides a snapshot of chemical exposure at a single point in time.
Our viewpoint is to regard the WSN as a discrete sampling of the geometric environment.
On the other hand, under discrete sampling, we express the dynamics of the upgraded fund price [??] (t) as
For details see [14]; Rowland Higgins has kindly reminded me that the discrete sampling theorem is due to Cauchy [19].
Discrete sampling implies the collection of one aliquot per individual sample interval, while composite sampling involves the combination of two or more aliquots from consecutive intervals to form a sample.
