Giver MATLAB code 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)
Revised Code
F0 =13; T0 =1/F0; Ts = 0.0001; t = 0:Ts:13*T0; x = real(exp(j*(2*pi*F0*t-pi/2))); plot(t,x) The problem was that the interval between points was too small. This created too few points to appear on the graph making the graph wrong.
