Window (WINDOW)

Window (WINDOW)

Property	Description	Units	Default	Range/Type
NSAMP	Number of input samples to window per invocation	None	64	[1, Inf)/Integer
WINDOW_LENGTH	Length of window in samples	None	16	[1, Inf)/Integer
WINDOW_SHIFT	Initial shift of window in samples	None	1	[0, Inf)/Integer
WINDOW_TYPE	0: Bartlett 1: Hanning 2: Rectangular 3: Hamming 4: Blackman 5: Blackman-Harris (3 term) 6: Blackman-Harris (4 term) 7: Gaussian (alpha=3) 8: De la Valle-Poussin.	None	0	[0, 8]/Integer
RIN	Input impedance	Ohm	Inf	(0, Inf]/Real
ROUT	Output impedance	Ohm	0	[0, Inf)/Real
Ports
Input	Input signal (real)
Output	Output signal (real)

Notes

1. This model windows a real signal using various window functions. During each invocation, this model processes NSAMP input samples. The number of samples windowed is determined by WINDOW_LENGTH. The position of the window’s left edge is determined by WINDOW_SHIFT.

Netlist Form

WINDOW:Name n1 n2 NSAMP=val WINDOW_LENGTH=val WINDOW_SHIFT=val WINDOW_TYPE=val [Rin=val][Rout=val]

Netlist Example

WINDOW:1 1 2 NSAMP=256 WINDOW_LENGTH=40 WINDOW_SHIFT=10 WINDOW_TYPE=2
