The following MATLAB code has a bug in it:

F0 =13;
T0 =1/F0;
Ts = 0.07;
t  = 0:Ts:13*T0;
x = real(exp(j*(2*pi*F0*t-pi/2)));
plot(t,x)

The bug is that Ts is far too large. Dividing by either 100 or 1000 will greatly improve the situation. The fixed code looks like

F0 =13;
T0 =1/F0;
Ts = 0.0007;
t  = 0:Ts:13*T0;
x = real(exp(j*(2*pi*F0*t-pi/2)));
plot(t,x)

Or

F0 =13;
T0 =1/F0;
Ts = 0.00007;
t  = 0:Ts:13*T0;
x = real(exp(j*(2*pi*F0*t-pi/2)));
plot(t,x)
