altes



Purpose
Altes signal in time domain.


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


Description
altes generates the Altes signal in the time domain.

Name Description Default value
N number of points in time  
fmin lower frequency bound (value of the hyperbolic instantaneous frequency law at the sample N), in normalized frequency 0.05
fmax upper frequency bound (value of the hyperbolic instantaneous frequency law at the first sample), in normalized frequency 0.5
alpha attenuation factor of the envelope 300
x time row vector containing the Altes signal samples  




Example
         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.
