Problem 10.4 - Frequency-Domain Transfer Function of an Op-Amp Circuit
*
* Hand-calculate the transfer function of the op-amp RC filter in
* general terms (literal solution, in terms of R and C). Calculate
* numerical values of the transfer function for specific values of
* R and C, using the five different values of radian frequency as
* given in the problem statement.
*
* Complete and run the PSpice program below. Use PROBE to obtain
* separate graphs of the amplitude and phase of the output voltage as
* a function of frequency. Also print out the amplitude and angle
* (also called the magnitude and phase) of the output voltage .
* Identify your hand-calculated values on the printed list and also on
* the PROBE graphs of the frequency response.
