Hi,
I have two signals that I need to block one of them (DC signal). The input signal is something like this:
Vin=VDC+Vac*Sin(2*pi*5*t)
1 millivolt<VDC<5 millivolt , .01 millivolt<Vac<.05 millivolt
I wanted to use a series capacitor for blocking but based on the low ac input frequency (5 Hz) it makes my capacitor very big. what is your suggestion for rejecting the VDC?
