lsim transfer function input
显示 更早的评论
Im trying to input the following fourier series (x) signal into my transfer function (H) with respect to time (tttime) using the the lsim function using the following code.
R=220;
a=.95;
C=1/(2*pi*5000*R);
num=[(R^2.*C^2) 0 1];
den=[(R^2.*C^2) (4.*R.*C.*(1-a)) 1];
H=tf(num, den);
%%Fourier Series
%ttfreqs = kw_o
%ttspect = Ck values
%tttime = time samples in seconds
%ttsignal = input signal
XM = repmat(ttspect.',[1, length(tttime)]);
basis = exp(1i.*ttfreqs.'*tttime);
x = sum(XM.*basis);
%plot(tttime,x);
lsim (H,x,tttime);
matlab is saying i have an error on my last line of code, whats the problem in here?
any help would appreciate it
thanks!

It's not posible to test your code

What is the error?
What are the values of ‘x’ and ‘tttime’?
