Part 2: The Rest of the Story
by Dan Cross-Cole
The second part of Danęs series moves from Digital Signal Processing
to using a QuickBASIC program for implementing audio band-pass filters
to provide a graphical display of the audio filter output. Combining
digital filters and Fast Fourier Transform can prove useful for several
applications, as illustrated in everything from measuring the response
from an acoustic guitar to isolating Morse code signals.

AN
INTELLIGENT SERIAL COMMAND INTERFACE |
|
|
|
by
Tom Napier
Specializing
has its perks. If a device is not available commercially today, the
opening is there for the taking. And, sometimes the development is
even fun. Tom knows that this is part of the joy of being a consultant,
as he runs through the process of designing a box to speed up the
testing of communications equipment.

THERMAL
CONSIDERATIONS IN ELECTRONICS DESIGN |
|
|
|
by George
Novacek
Options for thermal
management havenęt been abundant for electronics designers in the
past. Back before microprocessors, you were restricted in your choice
of cooling. Today, itęs a whole new story, as we see George detail
some practical and reliable hard-data examples arrived at through
the age-old method of measurement.

MULTIPLIER
TRICKS |
|
|
|
by Ingo Cyliax
Ingoęs back on the design track after
taking a trip through an FPGA module last time around. With everything
now in working order, he brings us integer multipliers. Used in many
signal processing applications, multipliers, of course, multiply.
But, look closer for some tricks to implement them.

Sieve of Eratosthenes
by George Martin
George changes
gears this time around as he trades problem solving for PC fun. In
this article, he reminds us about the old sieve of Eratosthenes and
goes about finding prime numbers using this technique as compared
to a more modern approach. All is meant to be an effort of enjoyment,
so put the tension aside and see what you can do with the power of
computing.

Tom Cantrell
In this article,
Tom revisits his 1998 presentation, ę8-bits: Onward and Upward,ę by
exploring the timelessness of the 8-bit MCU. The latest offering from
Cygnal Integrated Products, the ęC51, has hit the market proving once
again that you donęt have to sizzle like a Wunderchip to have a solid
bottom line.
