Hi,
I would like to use the RC filter with the Ferrite bead on the amplifier input to keep the frequency less than 1Hz and filter out the noisy signal which will go to the input of the amplifier. So, If I use the high resistance value like 1Mohm to meet my requirement (less than 1Hz). Then, the high resistance value will reduce the current flow, Right?. So, in this case, Did I get no current at the input of the amplifier?. If so, then, how do I filter out the signal to get lower than the 1Hz?.
And also, how to choose the ferrite bead?.
