    I'm working with PVDF for pressure measurements for underwater blast pressure measurements. the problem I have is the rising slope at the beginning of the signal after the first shock. I have done this testing with a PCB transducer with signal conditioning device and it eliminates this issue. I have that slope when I use it without the signal conditioner. My question is that is there a circuit I can make possibly from op amps which will prevent this slope and keep my signal on a constant zero line?

    Thanks!

    Here is what the signal looks like right now

    Helo,

    Do you have a schematic?
    Are there capacitors in the signal path?
    (it looks like a capacitor problem).
