I am working on a circuit where I need to seperate an AC and DC signal and then put it back togther. More specifically, on my input I have a 20-50VDC voltage and a 75mV - 150mV AC voltage. I have designed a highpass filter I want to pass the AC voltage through, but after designing it I realized that I was blocking the DC voltage. I would like to put the 20-50VDC voltage back onto the line after the AC voltages have been filtered. Any ideas? Thanks.
