hilbert
Discrete-time analytic signal computation of a real signal using Hilbert transform
Calling Sequence
x=hilbert(xr)
Arguments
- xr
real vector : the real signal samples
- x
Complex vector: the discrete-time analytic signal.
Description
Returns theanalytic signal, from a real data sequence.
The analytic signal x = xr + i*xi
has a real part, xr
, which
is the original data, and an imaginary part, xi
, which contains
the Hilbert transform. The imaginary part is a version of the
original real sequence with a 90° phase shift.
