Flat Top Window (Not in Base Package)

Applies a flat top window to the input sequence X. Details  Example

	X is the input signal.
	Flattop{X} is the input signal with the Flat Top window applied.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

Flat Top Window Details

If y represents the output sequence Flattop{X}, the Flat Top Window VI obtains the elements of y from

y_i = x_i[0.21557895 – 0.41663158cos(w) + 0.277263158cos(2w) – 0.083578947cos(3w) + 0.006947368cos(4w)]

for i = 0, 1, 2, …, n – 1

,

where n is the number of elements in X.
