In-Depth Information
• LPT8FAST.BAS is the same as ACQUIRE8.BAS, but provisions have been made to
allow acquired data to be recorded on disk. The compiled version (LPT8FAST.EXE)
of this program is intended to be run from a bootable diskette in which CONFIG.SYS
fi
first initializes a RAM drive.
• ATOD_SL8.BAS is similar to LPTAN8.BAS, but acquisition is regulated through the
TIMER command. Data frames are acquired at desired intervals in the range 1 to
86,400 seconds. ATOD_SL8.EXE is the compiled (DOS) version of this program.
• DTOA.BAS is a simple program that implements the serial protocol to write
values to the D/A converters. DTOA.EXE is the compiled (DOS) version of this
program.
• THERMOM.BAS is used to read temperature in °C and °F using a thermistor. THER-
MOM.EXE is the compiled (DOS) version of this program.
• SCALE.BAS implements an auto-zeroing digital scale by controlling the sensor's
output o
set through the Universal Sensor Interface's D/A. SCALE.EXE is the com-
piled (DOS) version of this program.

Folder: Spectral Analysis
• SPECTRUM.BAS is a QuickBASIC 4.5 program that estimates and displays the spec-
trum of a signal via the zero-padded FFT, an averaged-periodogram method (Welch's
estimator), and a parametric estimator (Marple's autoregressive method). SPEC-
TRUM.EXE is the compiled (DOS) version of this program.
• LPT8SPEC8.BAS is essentially the same as SPECTRUM.BAS but drives the Univer-
sal Sensor Interface to acquire evenly sampled data. LPT8SPEC.EXE is the compiled
(DOS) version of this program.
• MARPLE.DAT is a short 64-point complex test data set used to evaluate di
ff
erent
spectral analysis methods.
• NOISE.BAS is a QuickBASIC program to generate data useful for evaluating the
resolving power of spectral estimators. NOISE.DAT is an ASCII data
fi
file generated
through this program.

Signal Generators for the PC Sound Card
• BIP Electronics Labs Sine Wave Generator v3.0 (SINE30.ZIP, freeware for Windows
3.1, but works well in most cases under Windows 9x) by Marcel Veldhuijzen.
• Sweep Sine Wave Generator v2.0 (SWPGEN20.ZIP, freeware for Windows 9x) by
David Taylor.
• PC function generator (PLAY.EXE, freeware for Windows 9x, 2000, NT) by the
Physics Lab of Rutgers University.
• Sound interference (INTERFERENCE.EXE, freeware for Windows 9x, 2000, NT) by
the Physics Lab of Rutgers University. This program generates sine waves through
both channels of the sound card. The phase di
erence between the right and left chan-
nels can be set through software, allowing demonstrations of active noise control and
classical wave interference.
• Beat-tone generation (BEATINBRAIN.EXE, freeware for Windows 9x, 2000, NT)
by the Physics Lab of Rutgers University. This program generates two sine waves of
di
ff
erent frequencies through the left and right sound card, allowing experiments in
the generation and detection of beat tones.
