MATLAB CODE

%ECE 301
%Daniel Barjum
%HW 2B - Find the Bug

clear
clc

%The following code attempts to plot 13 cycles of
%a 13 Hz sinusoid, but it has a bug!


F0 = 13; 
T0 = 1/F0; 
Ts = 0.07;
t  = 0:Ts:13*T0; 
x = real(exp(j*(2*pi*F0*t-pi/2)));
subplot(2,1,1)
plot(t,x,'--r')
grid
title('Bugged Example');

%It does not plot 13 cycles of the wave!
%it only plots a little over one cycle.

%to make it plot thirteen cycles
%make the Ts value small enough
%i.e. 13 times smaller than T0.

F0 = 13; 
T0 = 1/F0; 
Ts = T0 / 13;
t  = 0:Ts:13*T0; 
x = real(exp(j*(2*pi*F0*t-pi/2)));
subplot(2,1,2)
plot(t,x)
grid
title('Correct Example');
