About Signal Operators

This signal operator is similar to the arithmetic mean signal operator above. Comparing
with the first formula for that signal operator above, to get the value at x2, we change
“Mean(a)” to “Mean(a, x2)”. In the integrations we change “min” to “x2-w/2”, “max” to
“x2+w/2”. Finally, instead of integrating “a(x)”, we change to integrating “a(x)/w” where
w is the width of the moving average “window”.

In general, the signal operator is implemented as a Centered Moving Average. If any
endpoint is missing for the calculation, it is calculated by interpolation.
