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-')
