The graph produced by this code is a wave that appears "blocky".  There reason for this is because the sampling step is too large.  By roducing it, Matlab will generate more points along the wave, fixing the form.  Below is an example of how to fix this problem:

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:

Homework 2_ECE301Fall2008mboutin - A - B - C - D - E

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)
