hello guys
I am a junior electronics engineer, I am working on this project related to metal detector I am facing this problem, the signal from op amp which I have circled is going into the analog switch (CD4066 IC) which I have circled but for some reason when the signal comes to output it is totally changed it reverted and for some reason even changed it shape, I dont get it why this could be happening , I can fix the signal by placing 10k resistor on output of switch to 12V the signal becomes like input but the second wave stays there , It should not be there.
