So we can look DC offset like a very low-frequency signal (mHz) then applying High-pass filter to extract it. I am confused that 1Hz is very low, then my cut-off frequency has to be under 1Hz, it seems not okay for a High-pass filter. I might to find out other way :)
Thank you very much for feedback.
I got your idea but I am gonna measure this with a microprocessor in portable application then I don't use PC, Oscillator.
Cheers.

Hi everyone,
I have a problem with extracting high DC dynamic offset from a signal to get a relatively small AC perturbation.
I have been struggling to find out the proper method but still no way out. I post this thread here hoping that someone would help me out of this
Here is my case:
