hilb - Hilbert transform

Calling Sequence

[xh]=hilb(n[,wtype][,par])

Parameters

• n : odd integer : number of points in filter
• wtype : string : window type ('re','tr','hn','hm','kr','ch') (default ='re')
• par : window parameter for wtype='kr' or 'ch' default par=[0 0] see the function window for more help
• xh : Hilbert transform

Description

returns the first n points of the Hilbert transform centred around the origin.

That is, xh=(2/(n*pi))*(sin(n*pi/2))^2.

Examples

plot(hilb(51))
