I have a signal that should have this theoretical shape:
The signal I am receiving experimentally has the following shape:
And here is a plot that better shows the shape of the waveform (I have clipped off most of the excess data):
Notice the large amount of what seems to be high frequency noise in the second plot and third plot. I am trying to figure out how to filter out the noise of the the experimental waveform with keeping the overall shape. I have considered using a low-pass filter or a voltage regulator but I am not sure if they will have the desired affect. Basically I need to keep the shape (and ideally magnitude) of the peak while filtering out the channel noise.
EDIT: Don't be concerned about the reflection of the theoretical peak in plot 1. This is just a direction change and is on no concern.
