Hi all i need to use the fft on an array of 5000000 values with fs=1e7 and plot it exactly. The shape is good but i'm very confused about the normalization for the fft. Someone can help me with a good code for the plot.
thx
Alessandro

It is all clearly and concisely explained in the text and code between the first two figures of the fft documentation.

My pleasure.
The window will filter the signals and remove much of the high-frequency energy.
