Linear interpolation
Quadratic interpolation
Linear interpolation is appropriate if the original waveform consists of straight lines, such as triangle or square waves. However, the peaks in waveforms with extremely sharp peaks may be flattened somewhat.
Quadratic interpolation is appropriate for waveforms with curves, such as sine waves. However, in waveforms with extremely sharp peaks, some peaks may become wider.

If the coordinate of the shifted point is X2 ', then the value of the point Y2 ' is given by the following formula.
Y2 + 0.2 Y1 ) (1 * 0.2) Y2
