Bugged 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 Fix
The graph produced by this code is a sinusoidal wave that appears "blocky". There reason for this is because the sampling rate is too large. The period of the wave is coded as 1/F0, which equals .0769. However, the value for Ts is .07, almost the size of one cycle. This problem can be fixed by reducing the value of Ts. Below is an example of this fix:
F0 =13; T0 =1/F0; Ts = 0.001; t = 0:Ts:13*T0; x = real(exp(j*(2*pi*F0*t-pi/2))); plot(t,x)
