Hi. I have the following signal. I am mainly interested in getting the peaks of the red signal. So I want to remove the part (background noise whose data I have) within the blue box.
1. How can I do it?
2. If I want to remove the noise, can I simply subtract the original values in time domain? something like:
y = Signal (t) - Noise (t)
or I have to do it in freq domain?
