Find the Bug
Given 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)
The Graph of the above MATLAB code
Revised Code
The revised MATLAB 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.
The graph of the revised code.
