Altes signal in time domain.
x=altes(N) x=altes(N,fmin) x=altes(N,fmin,fmax) x=altes(N,fmin,fmax,alpha)
number of points in time
lower frequency bound (value of the hyperbolic instantaneous frequency law at the sample N), in normalized frequency (default is .05).
upper frequency bound (value of the hyperbolic instantaneous frequency law at the first sample), in normalized frequency (default is 0.5).
attenuation factor of the envelope (default is 300).
time row vector containing the Altes signal samples.
altes generates the Altes signal in the time domain.
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. | ![]() | ![]() |
