Here we go. Running around in circles again, living a vicarious life.
If you think you can simulate a circuit and then build it, you are fooling yourself.
Component-operation is quite different to a simulation.
I thought you had actually built the circuit and were having problems.
In actual “life,” where are you going to get a 1Hz signal from?
Trying to pass a low frequency like this through an “AC set-up” is going to be very difficult.
If you have 1Hz, you need DC amplification.
That’s why I am saying, unless you tell us exactly what you are doing, we have absolutely no idea how to help you.
Everyone previously was going off at a tangent until I pulled you up and requested the circuit. Now we find you are still wanting things that are totally remote from the capability of the circuit you provided.
