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:4845973f-0da4-4dd3-ade0-64a7e55422d3]
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.
Any hints would be appreciated.
Thanks
