2. Let x[n] =cos((pi*n)/8) for -16 <= n <= 16 . On the same stem diagram, plot x(n) and x(n- 4). You should use the sigshift function to complete this exercise.
%matlab code
n=-16:16;
x=cos(pi*n/8);
x1=sigshift(x,4);
stem(x)
hold on
stem(x1,'-r')
function [y]=sigshift(x,m)
l=length(x);
y=x;
for i=1:l
if i<=m
y(i)=0;
else
y(i-m)=x(i);
end
end
end

x[n]=cos(2*pi*n) x[n]=cos(0.2*pi*n) x[n]=cos(0.25*pi*n) x[n]=cos(0.26*pi*n) x[n]=cos(10*pi*n) x[n]=cos((8/3)*pi*n) those signals are periodic?? and for those signals in Part (a) that are periodic, determine the number of samples per period
x[n]=cos(pi/8 *n^2) is periodic or non and explin it?
