'''Signal Spectrum from FFT'''

{{main|Fast Fourier Transform}}

: A [[fast fourier transform|FFT]] is used to compute the frequency spectrum of the signal. Usually there is a [[window function|windowing function]] option to limit [[spectral leakage]] and enhance frequency resolution.<ref>Agilent [httphttps://literature.cdn.keysight.com/litweb/pdf/59895990-1121EN6405EN.pdf], ''Agilent Vector Signal Analysis Basics'', pg. 12, Figure 8, accessed August 11, 2011.</ref> This window is implemented by multiplying it with the digitized values of the sample period before computing the FFT.
