Periodic signal revisited
1. I am considering my example x=cos2t from 0 to 5pi used in the previous homework part 1.E.
sampled at 0.01
but converting it to DT and increasing the sampling rate to 0.08 shows a non-periodic set of points
2. for making a periodic siganl lets take an example of $ X=\ e^t $
the graph of the function is
to convert it to periodic we use the following matlabcode
%referred the code of paul sceffler
clc
clear
t=.01:.01:1;
x=exp(t);
i=[];
for d=1:5
i=[i,x];
end
t=[.01:.01:5];
plot(t,i)
the periodic function thus is
