I am using a Fast Fourier Transform program to extract the frequency with max amplitude from a set of experimental data. Now, the program directly spits out the frequency along with the max amplitude. However, it provides no errors for either. So, to get the error in the frequency, i graph the output in the general viscinity of the frequency the program provided, and i see how wide the peak is at that frequency, and i take the error in frequency as the half-width of that peak at half the amplitude of the peak. Is there any similar way to provide an error for the amplitude of that peak?
Here is an example of the graph of the output near the highest peak of one of the sets of data
