This is the old page for the spring semester of 2000.
The new page will come soon!
The following errata have been found in the course notes:
- Page 2.8: The second
paragraph after definition of causal system should have been: The
systems in Examples 1 and 2 are causal. The systems in Examples 3 and 4
are noncausal.
- Page 3.4: The denominator
of r1,r2 should have been 2 (instead of 3).
- Page 7.2: Definition
of z transform should have a z^(-n), not z^n.
- Page 9.5: The first
term on the right-hand side should have (z-1)^2 in the denominator.
- Page 12.6:
"However, a PFE of Y(z) will then have the form"... The last
term in the PFE form should be B_(N-1)/z^(N-1), not B_(N-2)/z^(N-2).
- Page 12.6:"Now,
we are faced ..." The last term in the numerator of Y(z) should be
z^N - 1, not z^(N-1) - 1
- Page 22.1: The plot
should be centered at omega=0, not at omega=pi/2.
- Page 28.3: In the
third line of equations, the part inside the brackets reads:
( e^{j*Omega*T/2} - e^{-j*Omega*T/2} )
it should read: ( e^{-j*Omega*T/2} - e^{j*Omega*T/2} )
The rest of the proof is OK.
- Page 29.2: The Flash
A/D uses 2^N - 1 comparators, not 2^(N-1)
- Page 29.5: The
spectrum shown is spectrum of |F_a(Omega)|, not of F_a(Omega).
- Page 27.6: Spectrum of
Xd(w) should be limited to 2*pi*10^5*T, not 2*pi/T. Spectrum of Yd(w)
shoud be limited to pi/4, not pi/T.
 Page 50.5: 1) Zero-pad
{h(n)}n=0..M-1 with L (should be L-1) zeros ... Also, replace every
"M+L-1" with "M+L-2" for 1) and 2).
