stftb >> stftb > Other > gaussn

gaussn

generates the order n derivative of the gaussian window, centered at frequency f0

Calling Sequence

gn = gaussn(f0, n)

Parameters

f0:

a positive scalar in ]0 0.5], the normalized center frequency in (Hz).

n :

a positive integer; the order of derivation

gn :

a real row vector the coefficients of the nth order derivative.

Description

The wavelet gn is real, but it is its analytic form that is synthetized first. The real part is then normalized by the analytical value of its energy (so, L2 normalization!)
