Newbie level 6
Hello!
I need a little help with some analog design, my signal is a low frequency-signal about 0.2 - 5 Hz (~500mV pk-pk) with an DC offset for a couple of volts (2-4 V). This DC-level is not constant, it drops slowly over time.
Now I want to get rid of this DC-level and want my AC-signal lay between 0-1V (in this example).
To be clear, I want the min-value of the AC-signal to be my new baseline and want the signal to be positive.
How should I deal with this baseline problem, OP Amp feedback in some way?
Thanks...
