Fast Fourier Transform Demo

The time and frequency domains are represented on the left and right sides, respectively. All magnitudes are normalized.



Left clickSets real component
Right clickSets imaginary component
CONTROL-clickSets to 0
SHIFT-clickIsolates one value
OToggles origin (centre/left)
PToggles polar mode
GToggles frequency magnification
MShift data (SHIFT: Interpolates)
[ ]Changes data size (1-FFT to 256-FFT)
