* VS is the input for this circuit.  Say, it has a phasor amplitude of 1 volt in
* the F-domain and a sine waveform in the time domain, of 120 volt at 60 Hz.
* The following combination, independent, voltage source statement
* gives both the F and T domain specification.

* The 741 is modelled as simply as possible due to the
* limited number of transistors that can be simulated by
* the student version of pspice.  The model used is that
* of a voltage-controlled current source (VCCS) with unity
* gain.
