I'm working on a lab for school and I need a little help figuring out how to find the characteristic time for the FID. I have two signals: one looks like a sine function and the other a cosine function. They are each inside a decaying envelope (exp(-t/T)).

How do I determine T from the graph? Is it possible to use a Fourrier Transform?
