I have an assignment to simulate in and output in pspice and compare my results to what i messured in real life using functiongenerator, oscilloscope and generator. The problem is i dont know how to get the sinuscurved display when i simulate, i only get straight lines... I already have my messurements on paper where i calculated different frequencies then compared in and ut to see if it applified. I would really be grateful if you helped me guys :(
i only get straight lines
That's because: -
V2 is the wrong way round and there are no power supplies to the op-amps. Neither is there a ground connection along the bottom horizontal connection between V1 and R6.
