The correct answer is: A. Integrator.
An integrator is a type of control system that increases the steady state accuracy of a system by adding a time delay to the output signal. This time delay allows the system to “average out” any noise or disturbances in the input signal, resulting in a more accurate output signal.
A differentiator is a type of control system that increases the system’s response to changes in the input signal. This is done by taking the derivative of the input signal, which amplifies any changes in the signal. However, this can also lead to instability in the system, so it is important to use a differentiator with caution.
