I want to get the frequency response of a notch filter circuit in Proteus 7. The simulation gave good result. The hardware implementation also worked fine. When I tried to get the frequency response, error messages came up saying
i) AC analysis is not supported [refering to the oscilloscope]
ii)simulation failed due to simulator errors.
I would like to remind that the simulation worked and the digital oscilloscope showed expected waveform. The error log is attached below.
The schematic looks like this:
I cant figure out my mistake.
Thank you in advance
