Short-Time FFT
5-386
Dialog Box
Window type
The type of window to apply. (See the Window Function block reference.)
Tunable.
Stopband attenuation in dB
The level (dB) of stopband attenuation, R
s
, for the Chebyshev window.
Disabled for other
Window type selections. Tunable.
Beta
The β parameter for the Kaiser window. Disabled for other
Window type
selections. Increasing
Beta widens the mainlobe and decreases the
amplitude of the window sidelobes in the window’s frequency magnitude
response. Tunable.
Window sampling
The window sampling, symmetric or periodic. Tunable.
Inherit FFT length from input dimensions
When selected, uses the input frame size as the number of data points, N
fft
,
on which to perform the FFT.
FFT length
The number of data points, N
fft
, on which to perform the FFT. If N
fft
exceeds the input frame size, the frame is zero-padded as needed. This
