A-1 Creating two DT signals (one periodic and one non-periodic) from a periodic CT signal

I choose $ x(t) = sin (2\pi t), $ which is a periodic CT signal original plot:

Sampling delta t = 0.1, discrete dots become periodic signal:

non-period signal with delta t = 0.3

A-2 Create periodic signal with infinite number non=periodic signals

I use $ y=t $ adding infinite together

%MatLab code
t=0:0.001:10;
y=mod(t,2);
plot(t,y,'b-')
