Before Smoothing After Smoothing
Figure 3 Ć58: Smoothing
NOTE. Since smoothing is equivalent to low pass filtering, features of the
original waveform can be lost resulting in significant changes to the waveform.
To acquire appropriate output waveforms, experiment with a variety of values
for the Smooth +/– Points parameter.
H Side Effects from Shifting. The left side of Figure 3 -59 shows data prior to
shifting and the right side shows the result of shifting the data between the
cursors indicated with solid lines to right by 0.5. Since shifting to right by
0.5 requires determining the data at the 0.5 location to left, the data in Figure
3 -59 is interpolated to derive the data at locations 0.5 to left from the
positions of each data point. Linear interpolation is used in this case.
Original Data Data Shifted to Right by 0.5
Figure 3 Ć59: Data Shifting
When this data is output through an appropriate filter, the waveform will be
shifted to right by 0.5 point units. When this shift is performed, the data
point at the position of the left cursor is lowered. This is a side effect of the
interpolation process. There are several techniques for preventing this data
lowering phenomenon as follows.
1) Increase the size of the area.
