This is the original 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)
It outputs:
This code is wrong because the sampling frequency, Ts, is to large to get an accurate recreation of the signal. I fixed this bug by reducing the sampling time by a factor of 20-- Ts=.05*T0.
F0 = 13; T0 = 1/F0; Ts = .05*T0; t = 0:Ts:13*T0; x = real(exp(j*(2*pi*F0*t-pi/2))); Now the output looks like this: [[Image: Ece301_Hw2B.jpg _ECE301Fall2008mboutin| Fixed Plot]] plot(t,x)
