Hi all,
I need to calculate the gain and phase shift of the op amp below but I have no clue how to do it! If anyone can point me in the right direction, that would be great.
I have looked up op amps and can see a lot of info on the web but can't make sense of it because the diagrams and instructions I can find are of amps with two resistors, but this circuit has three so I don't know how to move on.....and my lecturer just had a heart attack so isnt there to help!
To clarify, we have completed an experiment using op amp boards and an oscilliscope to set up this circuit with an input signal of 1kHz and an amplitude of 100mV peak to peak. The frequency was changed in steps from 100 Hz up to 1,000,000 Hz and the Vin, Vout and period were measured then the phase shift and the gain were calculated at each step. I have to present these results and compare them to theoretical results so I need to know how to calculate the gain and phase shift given these perameters.

Any help would be great!! Thanks in advance![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
