Therefore this RC circuit performs the function of integration better and better
as the frequency is larger than
π RC12
(the gray area in Figure 7.32), which is
exactly the cutoff frequency of thecircuit.
Analyzing the graph, we gather that the circuit behaves as an integrator only
when the output voltage is a fraction of the input one. It would be useful then to
combine an amplication circuit (i.e., a circuit that increases ...
