To select the FFT window

■  There are  6  FFT  windows.  Each  one has  trade-offs  between  frequency  resolution  and
magnitude  accuracy.  What  you  want  to  measure  and  your  source  signal  characteristics
help  you  to  determine  which  window  to  use.  Use  the  following  guidelines  to  select  the
best window.

Type

Characteristics

Window

Hamming

Better solution for magnitude than Rectangle, and
good for frequency as well. It has slightly better
frequency resolution than Hanning.

Recommend to use for:

⚫

Sine, periodic and narrow band random noise.

⚫

Transients or bursts where the signal levels
before and after the event are significantly
different.

Rectangle

Best solution for frequency, worst for magnitude.

Best type for measuring the frequency spectrum of
nonrepetitive signals and measuring frequency
components near DC.

Recommend to use for:

⚫

Transients or bursts, the signal level before and
after the event are nearly equal.

⚫

Equal-amplitude sine waves with frequencies
those are very close.

⚫

Broadband random noise with a relatively slow
varying spectrum.

Blackman

Best solution for magnitude, worst for frequency.

Recommend to use for:

⚫

Single frequency waveforms, to find higher
order harmonics.

Hanning

Good for magnitude, but poorer frequency
resolution than Hamming.

Recommend to use for:

⚫

Sine, periodic and narrow band random noise.

⚫

Transients or bursts where the signal levels
before and after the event are significantly
different.
