The RCI-1B Integrator is a passive resistor-capacitor integrator
available with standard RC time constants of 1, 5, 10, or 100 microseconds.
The transfer function of the RCI-1 B Integrator is:
where S = jw = Laplace operator. This transfer function is that
of an integrator for sinusoidially varying voltages if the frequency
is large compared to 1/(2¶RC); or for transient voltages for
times small compared to RC.
The load impedance connected to the output
of the RCI-1B should have high input resistance and low input capacity.
