Ramp. Figure 2 is exactly what i need. I believe that is a ramp, however slight it is.

I need help with a circuit. I need to run the signal in first image through a circuit that can clean up the exponential rise and fall edges and make it more linear. Can anyone help. http://picasaweb.google.com/davidanthonypitts/SignalWaveforms?authkey=5iLxB--Xdqs#
