Greg’s ARM
Scope improves upon ordinary analog oscilloscopes
that don’t provide suitable results at low
speeds. The LPC2138-based system features
a timed PWM output for the more precise calibration
of the oscilloscope as well as an analog input
and an analog output with a graphical display.
As a result, the displayed signal is more
accurate at high or low speeds. p. 14
Keywords: Oscilloscope,
ARM, LPC2138, PWM, MCB2130, RS-232, UART,
ADC, DAC, LabVIEW |

Instrument Panel
A Simple Panel for Diesel Engines
Samir Lohani
With Samir’s
digital panel for diesel engines, you can view critical
engine-related data on a PC, HMI console, or Bluetooth-enabled
portable device. You can use the panel as a stand-alone
device or as a diesel engine’s preprocessor in a
PLC-based system. p. 22
Keywords: Instrument panel, engine, diesel, M16C/62P,
DAC, Bluetooth, RPM, pressure, serial, ADC, speech

Filter Figures
Ed
Nisley
Ed revisits
a filter design he worked on back in 2003, but this
time around, he has better instruments. Read on
for information about filter shapes, flatness, and
trade-offs with skirt steepness. He also describes
the effect a wider filter has on the output in the
application. p. 38
Keywords: Filtering, band-pass, double tuned, flatness,
harmonics

Visual Basic 2005 and the Serial Port
Aubrey Kagan
The capabilities
of Visual Basic 2005’s serial port model may seem
limited, but if you know what you’re doing, you
can definitely use it for numerous projects. Aubrey
recently got creative with Visual Basic 2005. Now
you can too. p. 44
Keywords: Visual Basic, serial, OOP, object, event,
method, control, data transmission, RS-232, reception

Third Overtone Crystal Clock Oscillator
Alan Bate
Alan describes
a requirement for a low-jitter, 54-MHz third overtone
design. It’s a good solution for high-volume manufacturing.
p. 54
Keywords: Crystal oscillator, third overtone, quartz,
modes, LC tank, accuracy, buffering, differential,
