How does background noise affect the fft results for a pure tone

It appears from a subsequent update that the OP may be making multiple experimental tests and tracking the mean of the magnitude of the DFT bin with noise added. This statistic is Ricean distributed, ...

How does background noise affect the fft results for a pure tone

I ensured there is no leakage by choosing a suitable sampling rate and duration. Here you can see the results of my DFT of a pure tone: Here you can see the results of my DFT of a pure tone + noise: ...
