Le 25/02/2017 à 19:17, Pablo Fonovich a écrit : Hi: This is the first time i work with discrete time transfers functions and Scilab. I want to use bode() for plotting the magnitud and phase response of the system, however, i don't understand how to set the frequencies to normalized values (-pi, pi). This is what i'm doing: s=poly(0,'s') H=(s^(-2400))/(1-0.5*s^(-2400)) S=syslin('d',H) bode(S) i get a warning that frequencies beyond nyquist rate are ignored and the resulting plot is attached. [cid:part1.AF505552.9295B9D5@inria.fr] In the help, it says that bode parameter could include fmin and fmax in herz, but isn't a discrete system response limited to normalized frequencies? And to transform the normalized frecuency to herz the sample rate must be used, but i don't know how to pass it to the system or something. S=syslin(dt,H) defines a dynamical system sampled. dt beeing the sampling period in second. If you want the frequency uniis be in rd/s add "rad" as last input argument Any hints would be appreciated.
