The same RC circuit with R and C connected in series can act as a differentiator if the output is taken across the resistor or it can act as an integrator if the output is taken across the capacitor.
The differentiator is basically a high pass filter. The output is the differentiation of the input hence it is named as differentiator. It has a very small time constant .
In the integrator the output is taken across the capacitor and integration of the input takes place. This circuit is basically a low pass filter. The time constant of this ciruit is very high.
