THE BUG

% Mark Frankosky
% hw2.2

F0 =13;

T0 =1/F0;

Ts = 0.07;

t  = 0:Ts:13*T0*13;

x = real(exp(j*2*pi*F0*t-pi/2));
% the bug was in the above line which read x = real(exp(j*(2*pi*F0*t-pi/2)));
% which would have been e^(j*2*pi*F0*t)*e^(-pi/2) which wouldnt have been
% the same as having a phase shift of pi/2 which is i guess what was
% needed.
