altes

Altes signal in time domain.

Calling Sequence

x=altes(N)
x=altes(N,fmin)
x=altes(N,fmin,fmax)
x=altes(N,fmin,fmax,alpha)

Parameters

N :

number of points in time

fmin :

lower frequency bound (value of the hyperbolic instantaneous frequency law at the sample N), in normalized frequency (default is .05).

fmax :

upper frequency bound (value of the hyperbolic instantaneous frequency law at the first sample), in normalized frequency (default is 0.5).

alpha :

attenuation factor of the envelope (default is 300).

x :

time row vector containing the Altes signal samples.

Description

altes generates the Altes signal in the time domain.

Examples

x=altes(128,0.1,0.45); plot(x);
//plots an Altes signal of 128 points whose normalized frequency goes from 0.45 down to 0.1.
