Histogram of the sampling interval distribution characterizing superimposed
periodic and additive sampling point streams
An illustration of this particular type of hybrid double sampling scheme is given
in Figure 10.9. The histogram showing the sampling interval distribution in this
case is given in Figure 10.10. It can be seen that this distribution of the sampling
intervals is closer to the desirable uniform distribution. It has been calculated
using the same conditions as those for the histogram displayed in Figure 10.8.
This histogram clearly shows that this kind of sampling provides acceptable
sampling conditions essential for an autocorrelation function estimation in the
