I have a current source that can output different types of waveform depending on the input, including DC (Howland current pump). I need to find a solution as to make sure that when DC is not required it does not appear at the output.
Basically here a series capacitor with the output of the circuit could give me that. It would allow to pass every waveform except for the DC one (when I need DC I could decouple that capacitor).
The problem is that when I attach a resistor as being load my signals could be damaged.
I use 1 Hz frequency, amplitudes from 1 V to let's say 50 Volts with mono and bipolar signals, saw-tooth, triangular signals.
This would look like a high pass filter, with cutoff at 1Hz.
