The following MATLAB code doesn't work properly since the step value, Ts, is too big. '''Code Containing the "Bug"''' 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) However, by reducing the step size, the MATLAB routine will print all 13 cycles of the 13Hz sinusoid. I chose to reduce the value by multiplying it by <math>10^-2</math>, which leaves us with Ts = 0.0007. The proper working code is shown below: '''Code After Reducing Ts Step Value''' 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)
