if u meant that what is the frequency of sample N in spectrum. it depends on sapmling rate.
according to the nyquist theorem samplin frequency must be at least 2 times of the most frequency of your signal.
the final frequency is the half of the sampling frequency of your signal.
new to matlab
% your signal is alittle strange because it's complex and so your frequency response don't have symetri in magnitude an asymetry in phase
a=0.88*exp(i*2*pi/5); % matlab use i instead of j
nn=0:40;
xn=a.^n;
n=128;
Xw=fftshift(fft(xn,n)); % u have to compute the frequency reponse...
if u want to work with AVRs have a look at **broken link removed** it could be usefull.
also Proteus is a very good simulation software for microconrollers.
in fact a frequency detector multiplies its input. therefor in the out put we have 2 terms with 2 different frequencies f1+f2 and f1-f2 where f1 and f2 are the frequencies of input signals of detector. the LPF elleminates the term of f1+f2 frequency.
help required
The output of a causal system is causal too.
Y(Z) is the out put of a causal system so it must be right sided and its roc is out side of the outer most pole.
X(jw) is the frequency response of x(t). X(w) can be the same or it might be simple notatin of X(e^jw) that is the frequency response of x[n] ( discrete time signal).
