Part 1
%Periodic signal t = 0:0.001:20; x = sin(t); plot(t,x)
%Periodic signal turned non-periodic by setting the sampling period to 0.1 F0 =13; T0 =1/F0; Ts = 0.1; t = 0:Ts:13*T0; x = sin(2*pi*F0*t); plot(t,x)
Part 2
%non-Periodic signal t = 0:0.001:20; x = exp(-t); plot(t,x)
%Made periodic
t = 1:0.01:6;
for I = 1:1:20
t = t + 6;
y1 = exp(-t+I*6);
plot(t,y1);
hold all
end
