Voltage Integrator

Changing the RC time constant and comparing differentiator output will illustrate this point.
1.33 Voltage Integrator
This component calculates the integral of the input voltage (the transfer function, 1/s) and
delivers it to the output. It is used in control systems and analog computing applications.
The true integrator function continuously adds the area under a curve for a specified time
interval.
For waveforms that are symmetrical about the zero axis, area above and below the axis is zero
and the resulting integrator output is zero.
For waveforms that are not symmetrical about the zero axis, the “areas” will be different. If
area above the axis is greater, integrator output will rise. If area is less, integrator output will
fall.
