Appendix F: Miscellaneous

Here is the equation for linear interpolation.

x±xi

f (x) + xi)1±xi {f (xi)1)±f (xi)} ) f (xi)

Here, i is the waveform point number; i takes integer values i = 1, 2, ..., n.

NOTE. The number of points can be increased or decreased, but the waveform may lose its characteristics when the number of points are decreased.

Example 1: 5 points padded to 9 points.
