hi..i wnt to know how the frequency-domain graph(FFT) is analyzed/studied? wht those high amplitude lines in the middle with lower amplitude lines following them to both the sides mean?
Wht does having low frequnecies in a signal mean? is it gud or a bad one?
Any help to clear my basic concepts wud b appreciated.
Thnx.
