FAQ: Why does the derivative look funny?

When taking a derivative and the result looks like the screenshot below, but a smoother signal is expected it is likely that the input signal is step interpolated.  To verify this, click on the item properties “I” on the input signal and check the interpolation method.

The interpolation method can be corrected by simply adding toLinear() in front of the derivative. See screen shot below of the formula.
