PHYS 217: Digital Electronics -- Spring 2008

HH = Horowitz and Hill: The Art of Electronics
 S = Scherz: Practical Electronics for Inventors

means read all of both sections, including, for example, section 12.3.9

--end of cycle 1 assignments--

Problem: given a truth table, express it as a simple boolean expression.

minterm=SOP, maxterm=POS
simplify the expression!

Karnaugh maps

S: 12.2.5

print out the file: http://www.physics.csbsju.edu/217/7segs.pdf
which shows 7 K-maps (for driving each segment a-g of a 7 segment display,
see 7-segments.html or S Fig 12.38 for further info) from an inputted
4-bit binary number: ABCD.  In 7segs.pdf the don't care states are 
shaded green (FYI: they correspond to unneeded binary numbers beyond 9, like 10=1010).
Directly on your hardcopy label/report what Boolean expression is
represented by each circled block of 1s.

Digital Signal Processing and the frequency domain

S 2.35 review Fourier series (but our application is sampled rather than continuous data)
S 8-8.7 (skim) basic analog filter design: definition of types
HH 5.04-5.05 (skim) characteristics of analog filters: definition of types

links in:
DSP.filter.design.html

Wiki: 
Discrete Fourier transform (skim: a bit too detailed/mathematical for our needs)
Digital signal processing
Digital filter
Finite impulse response
Infinite impulse response

The Mathematica code in
DSP.filter.m
displays the behavior of a for a Butterworth, 5th order, corner=1000, sampling=10000 filter
using the resursion relation found from
http://www-users.cs.york.ac.uk/~fisher/mkfilter/
(#3 in the jump page: DSP.filter.design.html)

HW: Use http://www-users.cs.york.ac.uk/~fisher/mkfilter/
to design a filter (you choose the parameters--but record them with your homework!).
Use Mathematica code similar to that above to display the
properties of your filter.  Print out a copy of your Mathematica
code and add (by hand) comments that explain what the code is doing.
You shoud make a Bode plot, plots that show the response to
a sinusoidal input (both a "passed" frequency and a "blocked" frequency), 
and the response to a step. Proper plots have axes labels (which you may put in
by hand).
