barthannwin {gsignal}

Modified Bartlett-Hann window

Description

Return the filter coefficients of a modified Bartlett-Hann window.

Usage

barthannwin(n)

Arguments

n

Window length, specified as a positive integer.

Details

Like Bartlett, Hann, and Hamming windows, the Bartlett-Hann window has a mainlobe at the origin and asymptotically decaying sidelobes on both sides. It is a linear combination of weighted Bartlett and Hann windows with near sidelobes lower than both Bartlett and Hann and with far sidelobes lower than both Bartlett and Hamming windows. The mainlobe width of the modified Bartlett-Hann window is not increased relative to either Bartlett or Hann window mainlobes.

Value

Modified Bartlett-Hann window, returned as a vector. If you specify a one-point window (n = 1), the value 1 is returned.
