Electroglottogram: First central difference...

Calculates an approximation of the derivative of the Electroglottogram.

Settings

Scale absolute peak at 0.99
defines whether the "derivative" should be scaled or not.

Algorithm

We take the first central difference, (dx(t)/dt)[i] = (x[i+1] - x[i-1])/(2Δt).

The real derivative can be found by using the Derivative... method.
