bohmanwin - Bohman window

Syntax

Description

w = bohmanwin(L) returns an L-point Bohman window in column vector w. A Bohman window is the convolution of two half-duration cosine lobes. In the time domain, it is the product of a triangular window and a single cycle of a cosine with a term added to set the first derivative to zero at the boundary. Bohman windows fall off as 1/w⁴.

Examples

Compute a 64-point Bohman window and display the result using WVTool:

L=64;
wvtool(bohmanwin(L))

Algorithms

The equation for computing the coefficients of a Bohman window is

where x is a length L vector of linearly spaced values generated using linspace. The first and last elements of the Bohman window are forced to be identically zero.
