function to generate input singals (rgs/rbs/prbs/sine)
Description
idinput
is a function for generating input signals (rgs/rbs/prbs/sine) for identification purposes
Usage
idinput(n, type = "rgs", band = c(0, 1), levels = c(-1, 1))
Arguments
n |
integer length of the input singal to be generated |
type |
the type of input signal to be generated. 'rgs' - generates random gaussian signal 'rbs' - generates random binary signal 'prbs' - generates pseudorandom binary signal 'sine' - generates a signal that is a sum of sinusoids Default value is type='rgs' |
band |
determines the frequency content of the signal. For type='rbs'/'sine'/, band = [wlow,whigh] which specifies the lower and the upper bound of the passband frequencies(expressed as fractions of Nyquist frequency). Default is c(0,1) For type='prbs', band=[0,B] where B is such that the singal is constant over 1/B (clock period). Default is c(0,1) |
levels |
row vector defining the input level. It is of the form levels=c(minu, maxu) For 'rbs','prbs', 'sine', the generated signal always between minu and maxu. For 'rgs', minu=mean value of signal minus one standard deviation and maxu=mean value of signal plus one standard deviation Default value is levels=c(-1,1) |
