Abstract
Techniques for compensating signal data from first order high pass filters for exponential decay to extract and underlying step function associated with the signal data. The techniques include adjusting a time scale of the signal data using a charge amplifier. The techniques also include determining a dynamic neutral point for the signal data using an exponential decay function. The techniques further apply an inverse transfer function to remove decay from the signal data and generate a step function associated with the signal data.
