It was definitely that circuit. On the worksheet we were given it says its a non-inverting amplifier and gives us that image then goes on to tell us to set up the circuit on the op amp board (DG2X34), set the input signal & amplitude and set the Vin with a frequency meter then obtain the Vout & period from the oscilliscope then calculate the gain and phase shift. I have done all of this without any trouble. It is just the theory I am having trouble with....and now you say its not actually a non-inverting amp.....and I cant get help from uni.....and I am starting to panic....just a bit!
